Crystal structure of tetra-kis-(?-n-butyrato-?(2) O:O')bis-[chlorido-rhenium(III)](Re-Re).

ABSTRACT: With an inversion center at the mid-point of the two Re(III) atoms, the title compound, [Re2Cl2{O2C(CH2)2CH3}4], exhibits a paddle-wheel or lantern-type structure with four n-butyrate groups bridging two Re(III) atoms in a syn-syn fashion. The axial chloride ligands together with the Re-Re quadruple bond [2.2330?(3)?Å] complete an essentially octa-hedral geometry around each Re(III) atom. There is little distortion, with an Re-Re-Cl bond angle of 176.18?(3)° and typical cis-O-Re-O bond angles ranging from 89.39?(11) to 90.68?(11)°. There are two mol-ecules in the unit cell, and no significant inter-molecular inter-actions were noticed between mol-ecules in the crystal.

Crystal structure of metronidazolium tetra-chlorido-aurate(III).

Project description:Metronidazole (MET) [systematic names: 1-(2-hy-droxy-eth-yl)-2-methyl-5-nitro-1H-imidazole and 2-(2-methyl-5-nitro-1H-imidazol-1-yl)ethanol] is a medication that is used to treat infections from a variety of anaerobic organisms. As with other imidazole derivatives, metronidazole is also susceptible to protonation. However, there are few reports of the structures of metronidazolium derivatives. In the title compound, (C6H10N3O3)[AuCl4] [systematic name: 1-(2-hy-droxy-eth-yl)-2-methyl-5-nitro-1H-imidazol-3-ium tetra-chlorido-aur-ate(III)], the asymmetric unit consists of a metronidazolium cation, [H(MET)](+), and a tetra-chlorido-aurate(III) anion, [AuCl4](-), in which the Au(III) ion is in a slightly distorted square-planar coordination environment. In the cation, the nitro group is essentially coplanar with the imidazole ring, as indicated by an O N-C=C torsion angle of -0.2 (4)°, while the hy-droxy-ethyl group is in a coiled conformation, with an O(H)-C-C-N torsion angle of 62.3 (3)°. In the crystal, the anion and cation are linked by an inter-molecular O-H⋯Cl hydrogen bond. In addition, the N-H group of the metronidazolium ion serves as a hydrogen-bond donor to the O atom of the hy-droxy-ethyl group of a symmetry-related mol-ecule, leading to the formation of chains along [010].

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.

Crystal structure of di-μ-isobutyrato-κ(4) O:O'-bis-[cis-di-chlorido-(dimethyl sulfoxide-κS)rhenium(III)].

Project description:The title compound, [Re2(C3H7COO)2Cl4{(CH3)2SO}2], comprises binuclear complex mol-ecules [Re-Re = 2.24502 (13) Å] involving cis-oriented double carboxyl-ate bridges, four equatorial chloride ions and two weakly bonded O atoms from dimethyl sulfoxide ligands in the axial positions at the Re(III) atoms. In the crystal, mol-ecules are linked into corrugated layers parallel to (101) by very weak C-H⋯Cl and C-H⋯O hydrogen-bonding inter-actions. C-H⋯Cl hydrogen bonding provides the links between layers to consolidate a three-dimensional framework.

Project description:The title compound bis-(1,4-diazo-niabi-cyclo-[2.2.2]octa-ne) di-μ-chlorido-bis-[tetra-chlorido-bis-muthate(III)] dihydrate, (C6H14N2)2[Bi2Cl10]·2H2O, was ob-tain-ed by slow evaporation at room temperature of a hydro-chloric aqueous solution (pH = 1) containing bis-muth(III) nitrate and 1,4-di-aza-bicyclo-[2.2.2]octane (DABCO) in a 1:2 molar ratio. The structure displays a two-dimensional arrangement parallel to (100) of isolated [Bi2Cl10](4-) bi-octa-hedra (site symmetry -1) separated by layers of organic 1,4-diazo-niabi-cyclo-[2.2.2]octane dications [(DABCOH2)(2+)] and water mol-ecules. O-H⋯Cl, N-H⋯O and N-H⋯Cl hydrogen bonds lead to additional cohesion of the structure.

Crystal structure of chlorido-{5,10,15,20-tetra-kis-[2-(2,2-di-methyl-propanamido)-phen-yl]porphyrinato-?(4) N}iron(III).

Project description:The title compound, [Fe(C64H64N8O4)Cl], is a five-coordinate square-pyramidal porphyrin complex with a chloride ion in the axial position, being coordinated from the protected side of the porphyrin; the Fe(III) atom is displaced by 0.474?(5)?Å from the 24-atom mean plane of the porphyrin core towards the chloride. The porphyrin moiety is a 'picket-fence' 5,10,15,20-tetra-kis-[2-(2,2-di-methyl-propanamido)-phen-yl]porph-yrinate (por) group. The Fe-Cl bond length is 2.221?(2)?Å and the Fe-N(por) bond lengths are in the range 2.043?(5)-2.063?(5)?Å. The supra-molecular architecture of the crystal is sustained by C-H?O inter-actions between the pyrrolic and phenyl H atoms of one mol-ecule and the carbonyl O atoms of the 2,2-di-methyl-propanamido groups of adjacent mol-ecules. The methyl groups of three of the four tert-butyl substituents exhibited rotational disorder over two positions. The investigated crystal was twinned by a twofold rotation about the (001) axis with a refined twin ratio of 0.4086?(16).

Crystal structure of bis-(quinolin-1-ium) tetra-chlorido-ferrate(III) chloride.

Project description:The asymmetric unit of the title hybrid compound, (C9H8N)[FeCl4]Cl, comprises a tetra-hedral tetra-chlorido-ferrate(III) anion, [FeCl4](-), a Cl(-) anion and two quinolinium cations. There are N-H?Cl hydrogen-bonding inter-actions between the protonated N atoms of the quinolinium cations and the chloride anion, which together with ?-? stacking between adjacent quinolinium rings [centroid-to-centroid distances between C6 and C5N rings in adjacent stacked quinolinium cations of 3.609?(2) and 3.802?(2)?Å] serve to hold the structure together.

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.

Crystal structure of chlorido-penta-kis(dimethyl sulfoxide-?O)chromium(III) dichloride.

Project description:In the complex cation of the title salt, [CrCl(C2H6OS)5]Cl2, the Cr(III) ion is coordinated by one chloride ligand and five O atoms from dimethyl sulfoxide (DMSO) ligands, leading to a slightly distorted octa-hedral coordination environment [O-Cr-O angles range from 86.69?(16) to 92.87?(16)°]. In the crystal, complex cations are arranged in hexa-gonally packed rows parallel to [010], with the chloride counter-anions situated in between. The inter-actions between cations and anions are mainly ionic in nature.
