Crystal structure of hexa-prop-2-en-1-yl 4,4',4'',4''',4'''',4'''''-[1,3,5,2λ(5),4λ(5),6λ(5)-tri-aza-triphosphinine-2,2,4,4,6,6-hexa-yl-hexa-kis-(-oxy)]hexa-benzoate.

ABSTRACT: In the title compound, C60H54N3O18P3, the central phosphazene ring is essentially planar, with an r.m.s. deviation of the six fitted atoms of 0.068 Å. The P-N bond lengths are within the narrow range 1.575 (2)-1.585 (2) Å, indicating the electrons are delocalized within the ring. The two ethenyl benzoate substituents on each P atom are located up and down with respect to the plane of the central P3N3 ring. The atoms of two terminal propenyl groups are disordered over two sets of sites, with refined site-occupancy ratios of 0.249 (12):0.751 (12) and 0.476 (9):0.524 (9). No intermolecular interactions are observed.

Crystal structure of hexa-methyl 4,4',4'',4''',4'''',4'''''-[(1,3,5,2λ5,4λ5,6λ5-tri-aza-triphosphinine-2,2,4,4,6,6-hexa-yl)hexa-kis-(-oxy)]hexa-benzoate.

Project description:The title compound, C48H42N3O18P3, achieved in a two-step synthesis, comprises a cyclo-triphosphazene core and six 4-meth-oxy-carbonyl-phen-oxy groups. Each P atom is attached to two substituents located up and down with respect to the plane of the phosphazene ring, the central P3N3 ring having a twist-boat conformation. The three O/P/O planes and five of the six benzene rings are nearly perpendicular to the mean plane through the phosphazene ring [dihedral angles = 82.98 (8)-88.92 (8)°], while the remaining benzene ring forms a dihedral angle of 25.72 (7)°. The crystal packing is stabilized by van der Waals inter-actions only.

2-[(2,4,4,6,6-Penta-chloro-1,3,5,2λ,4λ,6λ-triaza-triphosphinin-2-yl)aza-nid-yl]pyridinium.

Project description:The title compound, C(5)H(5)Cl(5)N(5)P(3), crystallizes as a zwitterion in which the pyridine N atom is protonated. An S(6) ring motif is formed via an intra-molecular C-H⋯N hydrogen bond. The triaza-triphosphinine ring adopts an envelope conformation, with one N atom displaced by 0.145 (1) Å from the other atoms. In the crystal, N-H⋯N and C-H⋯N hydrogen bonds link the mol-ecules into centrosymmetric dimers containing one R(2) (2)(7) ring motif and two R(2) (2)(8) ring motifs.

[μ(3)-2,2,4,4,6,6-Hexakis(3,5-dimethyl-pyrazol-1-yl)-2λ,4λ,6λ-1,3,5,2,4,6-triaza-triphosphinine]tris-[cis-dichloridopalladium(II)].

Project description:The title complex, [Pd(3)Cl(6)(C(30)H(42)N(15)P(3))], possesses C(3) mol-ecular symmetry. The P and N atoms of the cyclo-triphosphazene and the Pd atom are located on the crystallographic mirror plane. Each of the three symmetry-related Pd atoms is coordinated by two chloride ligands and two exocyclic pyrazolyl N atoms, but not by the cyclo-triphosphazene N atoms.

[μ-2,2,4,4,6,6-Hexakis(3,5-dimethyl-pyrazol-1-yl)-2λ,4λ,6λ-1,3,5,2,4,6-triaza-triphosphinine]bis-[bis-(nitrato- κO,O')cadmium(II)].

Project description:The complete title complex, [Cd(2)(NO(3))(4)(C(30)H(42)N(15)P(3))], is generated by crystallographic twofold symmetry, with one P and one N atom of the cyclo-triphosphazene ligand located on the rotation axis. The non-planar cyclo-triphosphazene ring accommodates two Cd ions, and only four out of six exocylcic pyrazolyl ligands are bound to the Cd metal atoms. Each of these two symmetry-related Cd atoms is coordinated by two bidentate nitrato ligands, two exocylic pyrazolyl N atoms, and one cyclo-triphosphazene N atom.

2,5-Bis[2-({bis-[3-(dimethyl-aza-nium-yl)prop-yl]aza-nium-yl}meth-yl)phen-yl]-1,3,4-oxadiazole hexa-kis-(perchlorate) sesquihydrate.

Project description:In the title hydrated salt, C36H66N8O(6+)·6ClO4(-)·1.5H2O, the asymmetric unit consists of a hexa-protonated [H6L](6+) cation, five perchlorate anions in general positions, two on twofold rotation axes (one of which is disordered), and two water mol-ecules of crystallization in general positions, one of them disordered around a twofold crystallographic axis. In the [H6L](6+) cation, two strong intra-molecular N-H⋯N hydrogen bonds occur, involving the N atoms of the oxadiazole ring as acceptors and the closest NH(+) groups of each dipropyl-enetriamine unit. In the crystal, the [H6L](6+) cations form channels along the a-axis direction, in which the perchlorate counter-ions and the water mol-ecules are lodged. The crystal packing features a network of N-H⋯O and O-H⋯O hydrogen bonds involving the NH(+) groups of the [H6L](6+) cation, the perchlorate anions and the water mol-ecules.

(2-Hydroxy-ethyl)(prop-yl)aza-nium 2-[(2-carboxy-phen-yl)disulfan-yl]benzoate monohydrate.

Project description:With the exception of the terminal hydr-oxy group [N-C-C-O = 53.8 (5)°], the cation of the title salt hydrate, C(5)H(14)NO(+)·C(14)H(9)O(4)S(2) (-.)H(2)O, is a straight chain. A twisted conformation is found for the anion [C-S-S-C = -87.44 (16)°]. In the crystal, the anions self-assemble into a helical supra-molecular chain via charge-assisted O-H⋯O(c) hydrogen bonds. These chains are connected into a three-dimensional network via N-H⋯O(c), N-H⋯O(w), O(h)-H⋯O(cb), and O(w)-H⋯O(c) hydrogen-bonding inter-actions (c = carboxyl-ate, w = water, h = hydr-oxy and cb = carbon-yl).

Methyl 2-[(methyl-sulfon-yl)(prop-yl)amino]benzoate.

Project description:The asymmetric unit of the title compound, C(12)H(17)NO(4)S, contains two mol-ecules, both of which show disorder of the two terminal C atoms of the propyl chain over two sets of sites with an occupancy ratio of 0.581 (6):0.419 (6). Intra-molecular C-H⋯O inter-actions help to establish the mol-ecular conformations: in one mol-ecule, the dihedral angle between the methyl ester group and the benzene ring is 41.0 (2)°, whereas in the other mol-ecule it is 36.12 (17)°. In the crystal, mol-ecules are linked by inter-molecular C-H⋯O and C-H⋯π inter-actions.

2-(4-Methyl-pyridin-2-yl)-4',4',6',6'-tetra-kis-(pyrrolidin-1-yl)-1H,2H-spiro-[naphtho-[1,2-e][1,3,2]oxaza-phosphinine-3,2'-[1,3,5,2,4,6]tri-aza-triphosphinine].

Project description:In the title spiro-phosphazene derivative, C33H46N9OP3, the phosphazene and six-membered N/O rings are in flattened chair and twisted-boat conformations, respectively. The naphthalene ring system and the pyridine ring are oriented at a dihedral angle of 41.82 (4)°. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules related by translation along the a axis into chains. C-H⋯π inter-actions aggregate these chains into layers parallel to the ab plane.

4,4'-Bis(prop-2-yn-yloxy)biphen-yl.

Project description:The title compound, C(18)H(14)O(2), crystallizes with one half-mol-ecule in the asymmetric unit. The mol-ecule lies on an inversion center, located at the mid-point of the central C-C bond. As a result, the benzene rings are coplanar. No classical hydrogen bonds or stacking inter-actions are observed in the crystal structure.

Tetra-kis(1,3,4,6,7,9-hexa-aza-1H-phen-alen-6-ium) sodium(I) penta-kis(tetra-fluorido-borate).

Project description:In the title compound, Na(+)·4C(7)H(5)N(6) (+)·5BF(4) (-), the Na(+) ion lies on a fourfold rotation axis and one of the tetra-fluoridoborate ions lies on a site of symmetry . Each Na(+) ion is surrounded by four symmetry-related tetra-fluoridoborate ions, and is eight-coordinated by F atoms, the Na⋯F separation being 2.3956 (15) or 2.4347 (17) Å. The hexa-azaphenalenium ring system is essentially planar. In the crystal structure, the cations and anions are linked into a three-dimensional network by N-H⋯N and C-H⋯F hydrogen bonds.
