Crystal structure of cis-aqua-bis-(2,2'-bi-pyridine-?(2) N,N')chlorido-chromium(III) tetra-chlorido-zincate determined from synchrotron data.

ABSTRACT: The structure of the title salt, [CrCl(C10H8N2)2(H2O)][ZnCl4], has been determined from synchrotron data. The Cr(III) ion is coordinated by four N atoms from two 2,2'-bi-pyridine (bipy) ligands, one O atom from a water mol-ecule and a chloride anion in a cis arrangement, displaying a distorted octa-hedral geometry. The tetra-hedral [ZnCl4](2-) anion is slightly distorted owing to its involvement in O-H?Cl hydrogen bonding with the coordinating water mol-ecule. The Cr-N(bipy) bond lengths are in the range 2.0485?(13)-2.0632?(12)?Å, while the Cr-Cl and Cr-(OH2) bond lengths are 2.2732?(6) and 1.9876?(12)?Å, respectively. In the crystal, mol-ecules are stacked along the a axis.

Crystal structure of cis-aqua-chlorido-bis-(1,10-phenanthroline-?(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.

Project description:In the asymmetric unit of the title compound, [CrF2(C5H5N)4][ZnCl3(C5H5N)]·H2O, there are two independent complex cations, one tri-chlorido-(pyridine-?N)zincate anion and one solvent water mol-ecule. The cations lie on inversion centers. The Cr(III) ions are coordinated by four pyridine (py) N atoms in the equatorial plane and two F atoms in a trans axial arrangement, displaying a slightly distorted octa-hedral geometry. The Cr-N(py) bond lengths are in the range 2.0873?(14) to 2.0926?(17)?Å while the Cr-F bond lengths are 1.8609?(10) and 1.8645?(10)?Å. The [ZnCl3(C5H5N)](-) anion has a distorted tetra-hedral geometry. The Cl atoms of the anion were refined as disordered over two sets of sites in a 0.631?(9):0.369?(9) ratio. In the crystal, two anions and two water mol-ecules are linked via O-H?Cl hydrogen bonds, forming centrosymmetric aggregates. In addition, weak C-H?Cl, C-H?? and ?-? stacking inter-actions [centroid-centroid distances = 3.712?(2) and 3.780?(2)Å] link the components of the structure into a three-dimensional network.

Crystal structure of cis-aqua-chlorido-(rac-5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-aza-cyclo-tetra-decane-κ(4) N)chromium(III) tetra-chlorido-zincate trihydrate from synchrotron data.

Project description:The structure of the title compound, cis-[CrCl(cycb)(H2O)][ZnCl4]·3H2O (cycb is rac-5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-aza-cyclo-tetra-decane; C16H36N4), has been determined from synchrotron data. In the complex cation, the Cr(III) ion is bound by four N atoms from the tetra-dentate cycb ligand, a chloride ion and one water mol-ecule in a cis arrangement, displaying a distorted octa-hedral coordination geometry. The distorted tetra-hedral [ZnCl4](2-) anion and three additional water mol-ecules remain outside the coordination sphere. The Cr-N(cycb) bond lengths are in the range of 2.0837 (14) to 2.1399 (12) Å while the Cr-Cl and Cr-(OH2) bond lengths are 2.2940 (8) and 2.0082 (13) Å, respectively. The crystal packing is stabilized by hydrogen-bonding inter-actions between the N-H groups of the macrocyclic ligand, the O-H groups of the water mol-ecules and the Cl atoms of the tetra-chlorido-zincate anion, leading to the formation of a three-dimensional network.

Project description: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 perchlorate anion was disordered over two sets of sites in a 0.868?(3):0.132?(3) ratio.

Each Zn(II) atom is coordinated in a distorted octa-hedral geometry by four O atoms and two N atoms from one water mol-ecule and two (py-2,5-dc)(2-) ligands, which also act as bridging ligands between Zn(II) atoms. ?-? Stacking inter-actions between two aromatic rings of (py-2,5-dc)(2-) fragments, with centroid-centroid distances of 3.4747?(7) and 3.7081?(7)?Å are observed. The crystal structure is stabilized by O-H?O and N-H?O hydrogen bonds.

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.
