First Evidence of Tris(catecholato)silicate Formation from Hydrolysis of an Alkyl Bis(catecholato)silicate.

ABSTRACT: The hydrolysis of 3-ammoniumpropylbis(catecholato)silicate 1, giving two different silica-based materials containing different amounts of tris(catecholato)silicate, is reported. The latter species can be formed through an attack of catechol to the silicon atom in the pentacoordinate complex, in which the silicon-carbon bond is further activated toward electrophilic proton cleavage. The Knoevenagel reaction was used as a probe in order to test the availability of functional groups on the surface of such materials.

Bis{tris-[3-(2-pyrid-yl)-1H-pyrazole]iron(II)} tetra-deca-molybdo(V,VI)silicate.

Project description:The asymmetric unit of the title compound, [Fe(C(8)H(7)N(3))(3)](2)[SiMo(14)O(44)], consists of a complex [Fe(C(8)H(7)N(3))(3)](2+) cation and half of a derivative of an α-Keggin-type anion, [SiMo(14)O(44)](4-). In the mixed-valent Mo(V/VI) anion, the α-Keggin type core is capped on two oppositely disposed tetra-gonal faces by additional (MoO(2)) units. The [SiMo(14)O(44)](4-) anion shows disorder. Two O atoms of the central SiO(4) group ( symmetry) are equally disordered about an inversion centre. Moreover, two of the outer bridging O atoms and the O atoms of the capping (MoO(2)) unit are likewise disordered. The Fe(2+) cation is surrounded in a slightly distorted octa-hedral coordination by six N atoms from three 3-(2-pyrid-yl)-1H-pyrazole ligands. N-H⋯O hydrogen bonding between the cations and anions leads to a consolidation of the structure.

Bis(catecholato)silanes: assessing, rationalizing and increasing silicon's Lewis superacidity.

Project description:Although bis(catecholato)silanes have been known for several decades, their substantial Lewis acidity is not yet well described in the literature. Herewith, the synthesis and characterization of multiple substituted bis(catecholato)silanes and their triethylphosphine oxide, fluoride and chloride ion adducts are reported. The Lewis acidity of bis(catecholato)silanes is assessed by effective (Gutmann-Beckett, catalytic efficiency), global (theoretical and relative experimental fluoride (FIA) and chloride (CIA) ion affinities) and intrinsic (electrophilicity index) scaling methods. This comprehensive set of experimental and theoretical results reveals their general Lewis acidic nature and provides a consistent Lewis acidity trend for bis(catecholato)silanes for the first time. All experimental findings are supported by high-level DLPNO-CCSD(T) based thermochemical data and the Lewis acidity is rationalized by complementary chemical bonding analysis tools. Against the common belief that inductive electron withdrawal is the most important criterion for strong Lewis acidity, the present work highlights the decisive role of π-back bonding effects in aromatic ring systems to enhance electron deficiency. Thus, bis(perbromocatecholato)silane is identified and synthesized as the new record holder for silicon Lewis superacids.

Tris(ethyl-enediamine)zinc(II) hexa-fluorido-silicate.

Project description:The title compound, [Zn(C(2)H(8)N(2))(3)](SiF(6)), was synthesized ionothermally using choline chloride-imidazolidone as solvent and template provider. In the crystal structure, the anions and cations are located on special positions of site symmetry 3.2 and show a typical octa-hedral geometry. The Zn(II) ion is coordinated by six N atoms from three ethyl-enediamine mol-ecules. The crystal structure displays weak hydrogen bonding between [SiF(6)](2-) anions and the ethyl-enediamine NH hydrogen atoms.

3-Chloropropylbis(catecholato)silicate as a Bifunctional Reagent for the One-Pot Synthesis of Tetrahydroquinolines from o-Bromosulfonamides.

Project description:Bis(catecholato)silicate salts are easily accessible reagents that can be used to install alkyl fragments through photoredox-enabled cross-coupling. These reagents can incorporate various functional groups including pendant alkyl halides. A halogenated organosilicate reagent was leveraged to develop a one-pot synthesis of tetrahydroquinolines from o-bromosulfonamides, where the bifunctional reagent participates in a nickel/photoredox cross-coupling followed by intramolecular nucleophilic substitution. The functional group tolerance of this cross-coupling strategy allowed for the preparation of a series of substituted tetrahydroquinolines.

Disodium tris-(dioxidomolybdenum) bis-(diarsenate).

Project description:The asymmetric unit of the title compound, Na(2)(MoO(2))(3)(As(2)O(7))(2), is composed of two cyclic MoAs(2)O(11) units and an MoO(6) corner-sharing octa-hedron. The anionic framework can be decomposed into two types of layers, viz. MoO(2)As(2)O(7) and Mo(2)As(2)O(14), which use mixed Mo-O-As and As-O-Mo bridges to achieve a new three-dimensional structure with two types of large channels in which the Na(+) cations are located. Two O atoms are disordered and are located in two positions close to their initial positions with occupancy ratios of 0.612 (17):0.388 (17) and 0.703 (12):0.298 (12).

Bis(catecholato-κ2 O,O')bis-(dimethyl sulfoxide-κO)titanium(IV).

Project description:Bis(benzene-1,2-diolato-κ2 O,O')bis-(dimethyl sulfoxide-κO)titanium(IV), [Ti(C6H4O2)2(C2H6OS)2], crystallizes with two crystallographically independent mol-ecules in the space group P21/c emulating ortho-rhom-bic Pbca symmetry (β = 90.0445 (9)°]. The two mol-ecules are related by pseudo-glide symmetry, broken by modulation of each one catecholate and dimethyl sulfoxide (DMSO) ligand. Twinning by pseudomerohedry was observed [twin ratio 0.5499 (7):0.4401 (7)]. Complex 3 was obtained by heating of diprotonated titanium tris-catecholate precursor 2H in DMSO, by formal displacement of a catechol mol-ecule by two DMSO mol-ecules. Complex 3 is just the second heteroleptic, mono-nuclear, neutral bis-catecholate complex with TiO6 metal coordination, the only other one being its bis-DMF analogue 6. The two mol-ecules of 3 exhibit a distorted octa-hedral geometry. The geometry and distortions from ideal symmetry of 3 are discussed and compared to 6 and to cationic tris-catecholate titanium complexes.

Tris(piperazinediium) bis-[tris-(pyridine-2,6-dicarboxyl-ato)neodymate(III)] 15.33-hydrate.

Project description:The title compound, (C(4)H(12)N(2))(3)[Nd(C(7)H(3)NO(4))(3)](2)·15.33H(2)O or (pipzH(2))(3)[Nd(pydc)(3)](2)·15.33H(2)O (in which pipz is piperazine and pydcH(2) is pyridine-2,6-dicarboxylic acid), was synthesized by the reaction of NdCl(3)·6H(2)O with the proton-transfer compound (pipzH(2))(pydc) in aqueous solution. The nine donor atoms of the three pydc(2-) ligands form a distorted tricapped trigonal-prismatic arrangement around the Nd(III) center. Considerable C-O⋯π stacking inter-actions between CO groups of carboxyl-ate fragments and aromatic rings of pydc(2-) with distances of 3.135 (5)-3.255 (5) Å are observed. In the crystal structure, a wide range of hydrogen-bonding [of the types O-H⋯O, N-H⋯O and C-H⋯O, with D⋯A distances ranging from 2.608 (10) to 3.278 (7) Å], ion-pairing and C-O⋯π stacking interactions connect the various components into a supra-molecular structure. There is a high degree of solvent disorder in the structure; the occupancies of five water molecules refined to 0.6, 0.5, 0.4, 0.25 and 0.25.

In the crystal structure, each Mo polyhedron has a square-anti-prismatic shape, while the Co complexes show distorted octa-hedral geometry with an occupancy of 50%. One of the Co atoms resides on a crystallographic inversion centre.

Bis[tris-(1,10-phenanthroline)nickel(II)] tris-[dicyanidoargentate(I)] nitrate 4.2-hydrate.

Project description:The title compound, [Ni(C(12)H(8)N(2))(3)](2)[Ag(CN)(2)](3)(NO(3))·4.2H(2)O, crystallizes with two independent [Ni(phen)(3)](2+) cations (phen is 1,10-phenanthroline; both Ni atoms have threefold symmetry and N(6) donor sets), three near-linear [Ag(CN)(2)](-) anions, one nitrate anion (N site symmetry 3) and 4.2 water mol-ecules of crystallization, some of which are disordered. The [Ag(CN)(2)](-) anions are situated within cavities created by the phenanthroline ligands of adjacent [Ni(phen)(3)](2+) cations. Some short C-H⋯O and C-H⋯N inter-actions may help to establish the packing.
