Investigation of nitro-nitrito photoisomerization: crystal structure of trans-chlorido-nitro-(1,4,8,11-tetra-aza-cyclo-tetra-decane-?4 N,N',N'',N''')cobalt(III) chloride.

ABSTRACT: The reaction cavity of the nitro group in the crystal of the title compound, [CoCl(NO2)(C10H24N4)]Cl, (I), was investigated to confirm that it offers sufficient free space for linkage isomerization to occur in accordance with the observed photochemical reactivity. The complex cation has crystallographic 2/m symmetry and the nitro and chloro ligands at the trans positions are statistically disordered. The complete cyclam ligand is generated by symmetry from a quarter of the mol-ecule. In the crystal of (I), the complex cations and Cl- ions are linked into a three-dimensional network by N-H?Cl(counter-ion) hydrogen bonds.

Crystal structure of trans-di-chlorido-(1,4,8,11-tetra-aza-cyclo-tetra-decane-?4 N)chromium(III) bis-(form-amide-?O)(1,4,8,11-tetra-aza-cyclo-tetra-decane-?4 N)chromium(III) bis-[tetra-chlorido-zincate(II)].

Project description:The structure of the title compound, [CrCl2(C10H24N4)][Cr(HCONH2)2(C10H24N4)][ZnCl4]2 (C10H24N4 = 1,4,8,11-tetra-aza-cyclo-tetra-decane, cyclam; HCONH2 = formamide, fa), has been determined from synchrotron X-ray data. The asymmetric unit contains two independent halves of the [CrCl2(cyclam)]+ and [Cr(fa)(cyclam)]3+ cations, and one tetra-chlorido-zincate anion. In each complex cation, the CrIII ion is coordinated by the four N atoms of the cyclam ligand in the equatorial plane and two Cl ligands or two O-bonded formamide mol-ecules in a trans axial arrangement, displaying a distorted octa-hedral geometry with crystallographic inversion symmetry. The Cr-N(cyclam) bond lengths are in the range 2.061?(2) to 2.074?(2)?Å, while the Cr-Cl and Cr-O(fa) bond distances are 2.3194?(7) and 1.9953?(19)?Å, respectively. The macrocyclic cyclam moieties adopt the centrosymmetric trans-III conformation with six- and five-membered chelate rings in chair and gauche conformations. The crystal structure is stabilized by inter-molecular hydrogen bonds involving the NH or CH groups of cyclam and the NH2 group of coordinated formamide as donors, and Cl atoms of the ZnCl4 2- anion as acceptors.

trans-(5,7,7,12,14,14-Hexamethyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-4,11-diene-κN,N',N'',N''')bis-(nitrito-κN)cobalt(III) perchlorate hemihydrate.

Project description:The asymmetric unit of the title Co(III) complex, [Co(NO(2))(2)(C(16)H(32)N(4))]ClO(4)·0.5H(2)O, comprises two complex cations, two perchlorate anions and a water mol-ecule of crystallization. The Co(III) atoms exist within distorted octa-hedral N(6) geometries defined by four N atoms of the macrocycle ligand and trans-N atoms derived from the nitrite anions. Systematic variations in the Co-N bond lengths are correlated with the presence of intra-molecular N-H⋯O(nitrite) hydrogen bonds. In the crystal, water-O-H⋯O(perchlorate) hydrogen bonds, involving one of the independent perchlorate anions only, lead to supra-molecular chains along the b-axis direction. The three-dimensional architecture is consolidated by numerous C-H⋯O inter-actions. The crystal studied was a non-merohedral, racemic twin.

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.

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.

Crystal structures of 5,12-dimethyl-1,4,8,11-tetra-aza-cyclo-tetra-decane cobalt(III) mono-phenyl-acetyl-ide and bis-phenyl-acetyl-ide.

Project description:Reported in this contribution are the synthesis and crystal structures of new mono- and bis-phenyl-acetyl-ides based on CoIII(DMC) (DMC is 5,12-dimethyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-ne). Chlorido-(5,12-dimethyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-ne)(phenyl-ethyn-yl)cobalt(III) chloride-aceto-nitrile-methanol (1/1/1), [Co(C8H5)Cl(C12H28N4)]Cl·CH3CN·CH3OH, 1, and (5,12-dimethyl-1,4,8,11-tetra-aza-cyclo-tetra-deca-ne)bis-(phenyl-ethyn-yl)cobalt(III) tri-fluoro-methane-sulfonate-di-chloro-methane (2/1), [Co(C8H5)2(C12H28N4)]2(CF3SO3)2·CH2Cl2, 2, were prepared under weak-base conditions in satisfactory yields. Single-crystal X-ray diffraction studies revealed that both 1 and 2 adopt a pseudo-octa-hedral symmetry in which the Cl-Co-C angles of 1 and C-Co-C of 2 range from 177.7 (2) to 178.0 (2)° and from 177.67 (9) to 179.67 (9)°, respectively. In both structures, the CoIII metal center is coordinated in the equatorial plane by four N atoms, in which the N-Co-N angles range from 85.6 (3) to 94.4 (3)°. The structure of 1 features two crystallographically independent mol-ecules in its triclinic cell (Z' = 2), which are related to each other by pseudo-monoclinic symmetry. The crystal investigated was twinned by a symmetry operator of the approximate double-volume C-centered cell (180° rotation around [201] of the actual triclinic cell), with a refined twin ratio of 0.798 (3) to 0.202 (3). Both methanol solvent mol-ecules in 1 are disordered, the major occupancy rates refined to 0.643 (16) and 0.357 (16). Compound 2 also contains two mol-ecules in the asymmetric unit, together with two tri-fluoro-methane-sulfonate anions [of which one is disordered; occupancy values of 0.503 (16) and 0.497 (16)] and a disordered di-chloro-methane [occupancy values of 0.545 (12) and 0.455 (12)].

Crystal structure of bis-[trans-(1,4,8,11-tetra-aza-cyclo-tetra-decane-?(4) N)bis-(thio-cyanato-?N)chromium(III)] tetra-chlorido-zincate from synchrotron data.

Project description:The structure of the title compound, [Cr(NCS)2(cyclam)]2[ZnCl4] (cyclam = 1,4,8,11-tetra-aza-cyclo-tetra-decane, C10H24N4), has been determined from synchrotron data. The asymmetric unit contains two independent halves of the Cr(III) complex cations and half of a tetra-chlorido-zincate anion. In each complex cation, the Cr(III) atom is coordinated by the four N atoms of the cyclam ligand in the equatorial plane and by two N-bound NCS(-) anions in a trans axial arrangement, displaying a distorted octa-hedral geometry with crystallographic inversion symmetry. 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.

Crystal structure of 1,4,8,11-tetra-methyl-1,4,8,11-tetra-azonia-cyclo-tetra-decane bis-[chlorido-chromate(VI)] dichloride from synchrotron X-ray data.

Project description:The crystal structure of title compound, (C14H36N4)[CrO3Cl]2Cl2, has been determined by synchrotron radiation X-ray crystallography at 220?K. The macrocyclic cation lies across a crystallographic inversion center and hence the asymmetric unit contains one half of the organic cation, one chloro-chromate anion and one chloride anion. Both the Cl- anion and chloro-chromate Cl atom are involved in hydrogen bonding. In the crystal, hydrogen bonds involving the 1,4,8,11-tetra-methyl-1,4,8,11-tetra-azonia-cyclo-tetra-decane (TMC) N-H groups and C-H groups as donor groups and three O atoms of the chloro-chromate and the chloride anion as acceptor groups link the components, giving rise to a three-dimensional network.

Diaqua-(1,4,8,11-tetra-aza-cyclo-tetra-decane-?N,N,N,N)copper(II) didodeca-noate dihydrate.

Project description:The title compound, [Cu(C(10)H(24)N(4))(H(2)O)(2)][CH(3)(CH(2))(10)CO(2)](2)·2H(2)O, consists of one cationic copper(II) complex, two dodeca-noate anions and two water solvent mol-ecules. The Cu(II) atom is located on an inversion center and is chelated by the four aza N atoms of the neutral 1,4,8,11-tetra-aza-cyclo-tetra-decane (cyclam) ligand and by two water mol-ecules in axial positions, giving an octa-hedral coordination geometry, distorted as a consequence of the Jahn-Teller effect. The uncoordinated water mol-ecules link the complex cations and the dodeca-noate counter-ions through O-H?O hydrogen bonding, forming a layer structure parallel to (001). Inter-molecular N-H?O inter-actions also occur.
