Aqua-tricarbon-yl(3,5,7-tribromo-tropolonato)rhenium(I) methanol solvate.

ABSTRACT: The title complex, [Re(C(7)H(2)Br(3)O(2))(CO)(3)(H(2)O)]·CH(3)OH, crystallized as a neutral Re(I) compound and one methanol solvent mol-ecule in the asymmetric unit. The metal centre is coordinated facially by three carbonyl groups. The bidentate tribromo-tropolanate ligand and a water mol-ecule complete the distorted octahedral coordination around the central metal. Inter-molecular Br?O [3.226?(5)?Å] and Br?Br [3.590?(2)?Å] contacts are observed between adjacent mol-ecules. These contacts, together with an array of O-H?O, O-H?Br and C-H?O hydrogen bonds, complete a three-dimensional polymeric network formed between the methanol solvent and the complex.

fac-Tricarbon-yl(pyridine-?N)(1,1,1-trifluoro-acetyl-acetonato-?O,O')rhenium(I).

Project description:In the title compound, [Re(C(5)H(4)F(3)O(2))(C(5)H(5)N)(CO)(3)], the Re(I) atom is six-coordinated owing to bonding by three carbonyl ligands arranged in a fac configuration, two O atoms from the bidentate 1,1,1-trifluoro-acetyl-acetonate ligand and an N atom from a pyridine ligand. In the crystal, the mol-ecules pack in layers, diagonally, in a head-to-tail fashion across the ab plane. These layers are stabilsed by inter-molecular C-H?O and C-H?F hydrogen bonds.

Three O atoms of the perchlorate anion are disordered over two positions with refined occupancy factors of 0.649?(7):0.351?(7).

Methyl [hydr-oxy(phen-yl)phosphono-meth-yl]phospho-nate methanol solvate.

Project description:The title compound, C(8)H(12)O(7)P(2)·CH(4)O, is a monoesterified bis-phospho-nate (or 1-hydroxy-methyl-ene-1,1-bis-phospho-nic acid). These synthetic compounds are widely used in medicine to inhibit bone resorption in diseases like osteoporosis, and are characterized by a stable P-C-P group and are thus analogs of inorganic pyrophosphate. By masking one or several ionizable groups, introduced as phosphono-ester, it was anti-cipated the formation of prodrugs with higher lipophilicity that could facilitate the drug delivery and metabolization. Mol-ecules are paired by inter-molecular hydrogen bonds involving the phospho-nic groups. In addition, dimers are connected side-by-side, building infinite ribbons along the a-axis direction; these ribbons are cross-linked perpendicularly along the b-axis direction via a methanol solvent mol-ecule (disordered over two sites with occupancy factors ca 0.6 and 0.4), forming an extended inter-molecular hydrogen-bonded network. The H atoms of the methyl group in the main molecule are disordered equally over two positions.

1,3,5-Tris(N-phenyl-benzimidazol-2-yl)benzene methanol solvate.

Project description:The main mol-ecule of the title compound, C(45)H(30)N(6)·CH(3)OH, has a non-planar core: the dihedral angles between the benzimidazole rings and the central benzene ring are 20.19?(10), 34.57?(8), and 44.59?(8)°, while the dihedral angles between the peripheral phenyl rings and the attached benzimidazole rings are 84.57?(7), 62.71?(6) and 51.73?(6)°. The tri-substituted benzene mol-ecule is connected to the methanol solvent mol-ecule through an O-H?N hydrogen bond, forming a 1:1 solvate. In the crystal structure, no significant ?-? inter-actions are present, and the mol-ecules are associated through weak C-H?N and C-H?O(methanol) contacts.

1,3-Bis(2-ethoxy-phen-yl)triazene methanol 0.33-solvate.

Project description:There are three independent mol-ecules of 1,3-bis-(2-ethoxy-phen-yl)triazene and a mol-ecule of methanol in the asymmetric unit of the title compound, C(16)H(19)N(3)O(2)·0.33CH(3)OH. Two mol-ecules related by a non-crystallographic pseudo-twofold rotation axis are linked via distinct inter-molecular N-H?N hydrogen bonds, leading to the formation of a dimer with an R(2) (2)(8) graph set. The third mol-ecule is connected to the methanol mol-ecule by O-H?N and N-H?O hydrogen bonds. There are a number of weak C-H?? inter-actions, with H?? distances ranging from 2.74 to 2.89?Å between the C-H groups and the aromatic benzene rings.

Project description:In the title compound, C(27)H(27)N(3)O(3)S(3)·CH(4)O, the dihedral angles formed by the mesitylene ring with the three oxopyridyl rings are 89.6?(1), 75.5?(1) and 80.69?(1)°, indicating that all three are nearly perpendicular to the mesitylene ring. Intra-molecular C-H?S hydrogen bonds generate S(6) ring motifs. The crystal structure is stabilized by intra-molecular C-H?S and inter-molecular C-H?O hydrogen bonds and weak C-H?? inter-actions.

Crystal structure of bromido-fac-tricarbon-yl[5-phenyl-3-(pyridin-2-yl)-1H-1,2,4-triazole-?(2) N,N']rhenium(I).

Project description:In the title compound, [ReBr(C13H10N4)(CO)3], the Re(I) atom has a distorted octa-hedral coordination environment. Two N atoms of the 5-phenyl-3-(pyridin-2-yl)-1H-1,2,4-triazole ligand and two of the three carbonyl groups occupy the equatorial plane of the complex, with the third carbonyl ligand and the bromide ligand in the axial positions. The three carbonyl ligands are arranged in a fac configuration around the Re(I) atom. Mutual N-H?Br hydrogen bonds arrange mol-ecules into centrosymmetric dimers. Additional stabilization within the crystal structure is provided by C-H?O and C-H?Br hydrogen bonds, as well as by slipped ?-? stacking inter-actions [centroid-to-centroid distance = 3.785?(5)?Å], defining a three-dimensional network.
