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

ABSTRACT: 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: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.

Bis(1,10-phenanthrolin-1-ium) tetra-chlorido-zincate monohydrate.

Project description:In the crystal structure of the title compound, (C12H9N2)2[ZnCl4]·H2O, the two independent 1,10-phenanthrolinium cations are bridged by the water mol-ecule and the tetrahedral tetrachloridozincate anion via N-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonds, forming chains along [100]. The chains are linked via C-H⋯Cl hydrogen bonds and a number of π-π inter-actions [centroid-centroid distances vary from 3.5594 (14) to 3.7057 (13) Å], forming a three-dimensional network. In each 1,10-phenanthrolinium cation, there is a short N-H⋯N inter-action.

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.

Tetra-chlorido(1,10-phenanthroline-?N,N')platinum(IV) monohydrate.

Project description:In the title complex, [PtCl(4)(C(12)H(8)N(2))]·H(2)O, the Pt(4+) ion is six-coordinated in a distorted octa-hedral environment by two N atoms of a 1,10-phenanthroline ligand and by four Cl atoms. As a result of the different trans effects of the N and Cl atoms, the Pt-Cl bonds trans to the N atom are slightly shorter than those trans to the Cl atom. The compound displays inter-molecular ?-? inter-actions between the six-membered rings, with a centroid-centroid distance of 3.834?Å. There are also weak intra-molecular C-H?Cl hydrogen bonds. According to the IR spectrum, solvent water was present in the crystal, but owing to the high thermal motion of the uncoordinated O atom, the H atoms could not be detected.

Project description:In the title compound, [Co(C(9)H(8)NO(3))(C(12)H(8)N(2))(2)(H(2)O)]NO(3)·H(2)O, the Co(II) atom is six-coordinated by a carboxylate O atom of the hippurate (Hc) anion, a water O atom and four N atoms from two 1,10-phenanthroline ligands in a distorted octa-hedral geometry. The uncoordinated O atom of the hippuric acid anion is involved in an intra-molecular hydrogen bond to the coordinated water mol-ecule. The crystal packing is stabilized by inter-molecular O-H?O hydrogen bonds involving the Hc anions, the coordinated water mol-ecule, the nitrate anion and the uncoordinated water mol-ecule.

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.
