Trans-Di-μ-acetato-[μ-N,N-bis-(diphenyl-phosphino)aniline]bis-[chlorido-molybdenum(II)](Mo-Mo)-dichloro-methane-tetra-hydro-furan (1/0.3/1.7).

ABSTRACT: The mol-ecular structure of the title compound, [Mo(2)(CH(3)COO)(2)Cl(2)(C(30)H(25)NP(2))]·0.3CH(2)Cl(2)·1.7C(4)H(8)O, features an Mo-Mo dumbbell bridged by two acetate groups which are trans to each other. Perpendicular to the plane spanned by the acetate groups, the Ph(2)PN(Ph)PPh(2) ligand bridges both Mo atoms, having a P-N-P angle of 114.09 (19)°. In a trans position to the PNP ligand are two Cl atoms, one on each molybdenum centre. The Mo-Mo bond distance is 2.1161 (9) Å, within the range known for Mo-Mo quadruple bonds. The Mo complex is located on a crystallographic twofold rotation axis which runs through the N-C bond of the ligand. The site occupation factors of the disordered solvent molecules were fixed to 0.15 for dichloromethane and 0.85 for tetrahydrofuran.

Bis[μ-bis-(diphenyl-phosphino)methane-κP:P']bis-[(chloro-difluoro-acetato-κO)silver(I)](Ag-Ag).

Project description:The asymmetric unit of the title compound, [Ag(2)(C(2)ClF(2)O(2))(2)(C(25)H(22)P(2))(2)], consists of two half-mol-ecules, each Ag(I) ion lying on a center of symmetry. In each complete mol-ecule, two bis-(diphenyl-phosphino)methane ligands bridge two Ag(I) ions, which are further coordinated by one chloro-difluoro-acetate ligand, giving T-shaped geometries and short intra-molecular Ag⋯Ag distances of 3.1078 (6) and 2.9950 (6) Å. In one mol-ecule, the unique -CF(2)Cl group is rotationally disordered over two sites with approximate occupancies of 0.53 and 0.47 for the major and minor components, respectively.

Di-μ-chlorido-bis-{[μ-1,8-bis-(diisopropyl-phosphan-yl)-9,10-dihydro-9,10-ethano-anthracene-κP:P']-μ-chlorido-μ-methyl-idene-dipalladium(II)} tetra-hydro-furan penta-solvate.

Project description:The title compound, [Pd(4)(CH(2))(2)Cl(4)(C(28)H(40)P(2))(2)]·5C(4)H(8)O, possesses a tetra-nuclear palladium core with four bridging chlorido ligands and two bridging methyl-ene units, as well as two bridging anthracene-based bis-phosphine ligands. This tetra-nuclear complex can be considered as being composed of two μ-chlorido-bridged LPd(2) units. The structural motif of these LPd(2) units shows two doubly bridged palladium centers between the P atoms of the bis-phosphine ligand. One of these bridges is a μ-Cl atom, the other a μ-methyl-ene group. The coordination environment around each palladium center is essentially square planar. We ascribe the oxidation state +II to the palladium centers and do not assume Pd-Pd bonds [shortest distances 2.8110 (5) and 2.8109 (6) Å]. Co-crystallized with the palladium complex we found five non-coordinating tetra-hydro-furan solvent mol-ecules, one of which is disordered over two positions in a 0.429 (9):0.571 (8) ratio.

Di-μ-chlorido-bis-{[2-(8-quinol-yloxy)-acetato-κN,O,O]copper(II)}.

Project description:The title compound, [Cu(2)(C(11)H(8)NO(3))(2)Cl(2)], is a bicopper(II) complex. Each Cu(II) ion is five-coordinated by two O atoms and one N atom from the (8-quinol-yloxy)acetate ligand, and by two μ(2)-chloride ligands, thus exhibiting a distorted square-pyramidal CuCl(2)NO(2) coordination environment. Each (8-quinol-yloxy)acetate anion acts as a tridentate chelating ligand. In the crystal structure, adjacent quinolyl rings are involved in strong π-π stacking inter-actions, with inter-planar distances of 3.549 (5) and 3.763 (5) Å, thereby forming a two-dimensional planar network perpendicular to the ab plane. Furthermore, a weak inter-action [2.750 (4) Å] is observed within these planes between one Cu(II) ion and a carboxyl-ate O atom from a ligand in an adjacent mol-ecule, which also contributes to the stability of the structure.

Di-μ-chlorido-bis-{chlorido[2,3-dimethyl-N-(pyridin-2-yl-methyl-idene)aniline-κ(2)N,N']mercury(II)}.

Project description:In the centrosymmetric binuclear molecule of the title complex, [Hg(2)Cl(4)(C(14)H(14)N(2))(2)], the five-coordinated Hg(II) ions have a distorted square-pyramidal geometry defined by two N atoms belonging to the chelating imino-pyridine ligand and three Cl atoms. The benzene and pyridine rings are oriented at a dihedral angle of 56.7 (6)°. The crystal packing is stabilized by C-H⋯Cl hydrogen bonds and π-π inter-actions between the pyridine rings [centroid-centroid distance = 3.796 (6) Å].

cis-Di-μ-oxido-bis-[(N,N-diethyl-dithio-carbamato-κS,S')oxidomolybdenum(V)](Mo-Mo) tetra-hydro-furan monosolvate.

Project description:The title compound, [Mo(2)(C(5)H(10)NS(2))(2)O(4)]·C(4)H(8)O, can be readily prepared in tetra-hydro-furan (THF) by an oxidation reaction between the Mo(IV) precursor [MoO(S(2)CNEt(2))(2)] with [ReMeO(3)]. The compound is an axially symmetric Mo(V) dimer (2 symmetry), in which the metal atoms exhibit a distorted square-pyramidal coordination environment. A THF mol-ecule was found to be equally disordered over two symmetry-related sites (around a twofold rotation axis), trans-coordinated to the apical oxido group and weakly inter-acting with the Mo(V) atoms [Mo-O = 2.6213 (19) Å]. In the crystal, some weak C-H⋯O inter-actions occur between the terminal oxido and neighbouring -CH(3) groups of an adjacent [Mo(μ-O)O(S(2)CNEt(2))](2) unit.

N,N-Bis(diphenyl-thio-phosphino-yl)-4-ethyl-aniline.

Project description:The title compound, C32H29NP2S2, has two mol-ecules in the asymmetric unit, with an r.m.s. difference of 0.218 Å in their best-fit overlay. Both mol-ecules have a slightly distorted trigonal-planar N atom, bonded to two P(V) atoms and a C atom of the 4-ethyl-phenyl unit. The P-N-P angles of 126.34 (11) and 125.98 (11)° are larger than the four C-N-P bond angles. The two S atoms are trans to one another with respect to the P-N-P angle. The crystal structure features C-H⋯π inter-actions. The methyl group in one of the mol-ecules is disordered over two sets of sites, with occupancies of 0.518 (6) and 0.482 (6).

Di-μ-chlorido-bis-[diacetonitrile-chlorido-oxidovanadium(IV)].

Project description:The title compound, [V(2)Cl(4)O(2)(CH(3)CN)(4)], is a centrosymmetric dinuclear V(IV) complex associated with four mol-ecules of acetonitrile. The coordination around both V(IV) atoms is essentially square-planar, involving three Cl atoms and one O atom [maximum deviation = 0.017 (3) Å for the O atom]. The augmented octahedral coordination of the metal atom is completed by the N atoms of acetonitrile ligands. The V(IV) atoms are linked by two Cl atoms, acting as bridging atoms. The crystal studied was a non-merohedral twin with a ratio of the two twin components of 0.8200 (3):0.1800 (3). Although Cl and O atoms are present as potential acceptors in the title compound, no hydrogen bonds were observed in the crystal structure.
