Bis[trans-di-fluorido-tetra-kis-(pyridine-?N)chromium(III)] sodium tetra-chlorido-zincate perchlorate from synchrotron data.

ABSTRACT: The title salt, Na[CrF2(C5H5N)4]2[ZnCl4]ClO4, consists of two cationic Cr(III) complexes, an Na(+) cation, one [ZnCl4](2-) anion and one ClO4 (-) anion. The Cr(III) atoms are coordinated by four pyridine (py) N atoms and two F atoms in a trans arrangement, displaying a distorted octa-hedral geometry. The mean Cr-N(py) and Cr-F bond lengths are 2.086?(8) and 1.864?(14)?Å, respectively. The [ZnCl4](2-) anion has a distorted tetra-hedral geometry. The most notable feature of the crystal packing is the formation of weak pyridine-perchlorate C-H?O hydrogen bonds, resulting in supra-molecular chains along the b-axis direction. The perchlorate anion was disordered over two sets of sites in a 0.868?(3):0.132?(3) ratio.

Crystal structure of trans-diammine(1,4,8,11-tetra-aza-cyclo-tetra-decane-κ(4) N)chromium(III) tetra-chlorido-zincate chloride monohydrate from synchrotron data.

Project description:The asymmetric unit of the title complex salt, [Cr(C10H24N4)(NH3)2][ZnCl4]Cl·H2O, is comprised of four halves of the Cr(III) complex cations (the counterparts being generated by application of inversion symmetry), two tetra-chlorido-zincate anions, two chloride anions and two water mol-ecules. Each Cr(III) ion is coordinated by the four N atoms of the cyclam (1,4,8,11-tetra-aza-cyclo-tetra-deca-ne) ligand in the equatorial plane and by two N atoms of ammine ligands in axial positions, displaying an overall distorted octa-hedral coordination environment. The Cr-N(cyclam) bond lengths range from 2.0501 (15) to 2.0615 (15) Å, while the Cr-(NH3) bond lengths range from 2.0976 (13) to 2.1062 (13) Å. The macrocyclic cyclam moieties adopt the trans-III conformation with six- and five-membered chelate rings in chair and gauche conformations. The [ZnCl4](2-) anions have a slightly distorted tetra-hedral shape. In the crystal, the Cl(-) anions link the complex cations, as well as the solvent water mol-ecules, through N-H⋯Cl and O-H⋯Cl hydrogen-bonding inter-actions. The supra-molecular set-up also includes N-H⋯Cl, C-H⋯Cl, N-H⋯O and O-H⋯Cl hydrogen bonding between N-H or C-H groups of cyclam, ammine N-H and water O-H donor groups, and O atoms of the water mol-ecules, Cl(-) anions or Cl atoms of the [ZnCl4](2-) anions as acceptors, leading to a three-dimensional network structure.

The mean Cr-N(cyclam) and Cr-N(NCS) bond lengths are 2.065?(4) and 1.995?(6)?Å, respectively. The macrocyclic cyclam moieties adopt centrosymmetric trans-III configurations with six- and five-membered chelate rings in chair and gauche configurations, respectively. The [ZnCl4](2-) anion, which lies about a twofold rotation axis, has a slightly distorted tetra-hedral geometry. The crystal packing is stabilized by hydrogen-bonding inter-actions between the N-H groups of the cyclam ligands, the S atoms of the NCS(-) groups and the Cl(-) ligands of the anion.

Project description:The structure of the title complex, [CrCl2(2,3,2-tet)]ClO4 (2,3,2-tet is 1,4,8,11-tetra-aza-undecane, C7H20N4), has been determined from synchrotron data. The Cr(III) ion is coordinated by the four N atoms of the 1,4,8,11-tetra-aza-undecane ligand in the equatorial plane and two chloride ions in an axial arrangement, displaying a slightly distorted octa-hedral coordination environment. The two H atoms of the secondary amines are grouped on the same side of the equatorial N4 plane (meso-RS conformation). The Cr-N bond lengths range from 2.069 (2) to 2.084 (2) Å, while the mean Cr-Cl bond length is 2.325 (2) Å. The crystal structure is stabilized by inter-molecular hydrogen-bonding inter-actions between the primary and secondary amine groups of the 2,3,2-tet ligands, the Cl ligands and the O atoms of the perchlorate counter-anion, forming corrugated layers parallel to (010).

Crystal structure of tris-(trans-1,2-cyclo-hexa-ne-diamine-?(2) N,N')chromium(III) tetra-chlorido-zincate chloride trihydrate from synchrotron data.

Project description:The structure of the title double salt, [Cr(rac-chxn)3][ZnCl4]Cl·3H2O (chxn is trans-1,2-cyclo-hexa-nedi-amine; C6H14N2), has been determined from synchrotron data. The Cr(III) ion is coordinated by six N atoms of three chelating chxn ligands, displaying a slightly distorted octa-hedral coordination environment. The distorted tetra-hedral [ZnCl4](2-) anion, the isolated Cl(-) anion and three lattice water mol-ecules remain outside the coordination sphere. The Cr-N(chxn) bond lengths are in a narrow range between 2.0737?(12) and 2.0928?(12)?Å; the mean N-Cr-N bite angle is 82.1?(4)°. The crystal packing is stabilized by hydrogen-bonding inter-actions between the amino groups of the chxn ligands and the water mol-ecules as donor groups, and O atoms of the water mol-ecules, chloride anions and Cl atoms of the [ZnCl4](2-) anions as acceptor groups, leading to the formation of a three-dimensional network. The [ZnCl4](2-) anion is disordered over two sets of sites with an occupancy ratio of 0.94:0.06.

Crystal structure of cis-aqua-chlorido-bis-(1,10-phenanthroline-κ(2) N,N')chromium(III) tetra-chlorido-zincate monohydrate from synchrotron data.

Project description:The structure of the title compound, [CrCl(C12H8N2)2(H2O)][ZnCl4]·H2O, has been determined from synchrotron data. The Cr(III) ion is bonded to four N atoms from two 1,10-phenanthroline (phen) ligands, one water mol-ecule and a Cl atom in a cis arrangement, displaying an overall distorted octa-hedral coordination environment. The Cr-N(phen) bond lengths are in the range of 2.0495 (18) to 2.0831 (18) Å, while the Cr-Cl and Cr-(OH2) bond lengths are 2.2734 (7) and 1.9986 (17) Å, respectively. The tetra-hedral [ZnCl4](2-) anion is slightly distorted owing to its involvement in O-H⋯Cl hydrogen bonding with coordinating and non-coordinating water mol-ecules. The two types of water mol-ecules also inter-act through O-H⋯O hydrogen bonds. The observed hydrogen-bonding pattern leads to the formation of a three-dimensional network structure.
