Bis[trans-dichloridobis(propane-1,3-diamine-?(2)N,N')chromium(III)] tetra-chloridozincate determined using synchrotron radiation.

ABSTRACT: In the title compound, [CrCl(2)(C(3)H(10)N(2))(2)](2)[ZnCl(4)], the Cr(III) atom is coordinated by four N atoms of propane-1,3-diamine (tn) and two Cl atoms in a trans arrangement, displaying a distorted octa-hedral geometry with crystallographic inversion symmetry; the Zn atom in the [ZnCl(4)](2-) anion lies on a -4 axis. The orientations of the two six-membered chelate rings in the complex cation are in an anti chair-chair conformation with respect to each other. The Cr-N bond lengths are 2.087?(6) and 2.097?(6)?Å. The Cr-Cl and Zn-Cl bond lengths are 2.3151?(16) and 2.3255?(13)?Å, respectively. Weak inter-molecular hydrogen bonds involving the tn NH(2) groups as donors and chloride ligands of the anion and cation as acceptors are observed.

Project description:In the title compound, [CrCl(2)(C(3)H(10)N(2))(2)]ClO(4), the Cr(III) atom is coordinated equatorially by four N atoms of two propane-1,3-diamine (tn) ligands and axially by two mutually trans Cl atoms, thus displaying a slightly distorted octa-hedral geometry with no crystallographically imposed symmetry. The two six-membered chair chelate rings in the complex cation are in an anti conformation with respect to each other. The Cr-N bond lengths range from 2.0831 (18) to 2.0917 (19) Å, and the Cr-Cl bond lengths are 2.3148 (6) and 2.3135 (6) Å. The perchlorate anions have slightly distorted tetra-hedral geometries. Weak inter-molecular hydrogen bonds involving the tn ligand NH groups as donors, and chloride ligands and anion O atoms as acceptors are observed.

trans-Dichloridobis(2,2-dimethyl-prop-ane-1,3-diamine-?N,N')chromium(III) perchlorate.

Project description:In the title salt, [CrCl(2)(C(5)H(14)N(2))(2)]ClO(4), the Cr atom is in a trans-CrCl(2)N(4) octa-hedral environment comprising the four N atoms of two chelating 2,2-dimethyl-propane-1,3-diamine ligands and two Cl atoms. The two six-membered CrC(3)N(2) rings in the cation adopt anti chair-chair conformations with respect to each other. The perchlorate anion is disordered over two positions in respect of the Cl and an O atom in a 6:4 ratio. N-H?O hydrogen bonds link the cations and anions into a layer structure.

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.

trans-Di-fluorido-tetra-kis-(pyridine-?N)chromium(III) perchlorate from synchrotron radiation.

Project description:The are two independent complex cations in the title salt, [CrF2(C5H5N)4]ClO4, each located on a centre of inversion, as well as an independent perchlorate counter-ion. The complex cations adopt slightly distorted octa-hedral coordination environments around the Cr(III) ion, defined by four pyridine (py) N atoms in the equatorial plane and two F(-) ligands in the axial positions; intra-molecular C-H?F contacts are noted. The mean Cr-N(py) and Cr-F bond lengths are 2.088?(6) and 1.8559?(10)?Å, respectively. The three-dimensional architecture is sustained by hydrogen bonds involving the pyridine C-H groups as donors, and F and O atoms as acceptors.

Crystal structure of trans-di-chlorido-(1,4,8,11-tetra-aza-undecane-?(4) N)chromium(III) perchlorate determined from synchrotron data.

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).

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

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 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.
