The crystal structures of tetra-kis-(?-n-butyrato-?(2) O:O')bis[bromidorhenium(III)] and tetra-kis-(?-n-butyrato-?(2) O:O')bis[chlorido-rhenium(III)] aceto-nitrile disolvate.

ABSTRACT: The title complexes, [Re2Br2(O2CC3H7)4], (1), and [Re2(O2CC3H7)4Cl2]·2CH3CN, (2), both exhibit paddlewheel structures with four carboxyl-ate ligands bridging two Re(III) atoms. The Re-Re distances are 2.2325?(2) and 2.2299?(3)?Å, indicating quadruple bonds between the Re(III) atoms in each complex. Both complexes contain an inversion center at the mid-point of the Re-Re bond. The Re-Br bond [2.6712?(3)?Å] in (1) is 0.1656?(6)?Å longer than the Re-Cl distance [2.5056?(5)?Å] of (2). In (2), the N atom of each co-crystallized aceto-nitrile solvent mol-ecule is nearly equidistant between and in close contact with two carboxyl-ate C atoms.

Diammine(2,2'-bipyridine)-bis(thio-cyan-ato--?N)cobalt(III) diamminetetra-kis(thio-cyanato--?N)chromate(III) aceto-nitrile disolvate.

Project description:The new heterometallic title complex, [Co(NCS)(2)(C(10)H(8)N(2))(NH(3))(2)][Cr(NCS)(4)(NH(3))(2)]·2CH(3)CN, has been prepared using the open-air reaction of cobalt powder, Reineckes salt and 2,2'-bipyridine (dpy) in acetonitrile. The crystal structure consists of discrete cationic [Co(NCS)(2)(NH(3))(2)(dpy)](+) and anionic [Cr(NCS)(4)(NH(3))(2)](-) building blocks, both with 2 symmetry, and acetonitrile solvent mol-ecules, which are linked together by N-H?N hydrogen bonds, forming extended supra-molecular chains. Furthermore, N-H?S, C-H?S and C-H?N hydrogen bonds inter-link neighbouring chains into a three-dimensional framework. The Co atom is in an elongated octa-hedral coordination environment with two N atoms from the dpy ligands and two NCS-groups in the equatorial plane and with two NH(3) mol-ecules at the axial positions. The Cr(III) ion is octa-hedraly coordinated by two NH(3) mol-ecules at the axial positions and four NCS-groups in the equatorial plane. Intensity statistics indicated non-merohedral twinning with the twin matrix [100; 0[Formula: see text]0; [Formula: see text]0[Formula: see text]]. The refined ratio of the twin components is 0.530?(1):0.470?(1).

Crystal structures of (aceto-nitrile-?N)tris-(pyridine-4-thio-amide-?N)bis-(thio-cyanate-?N)cobalt(II) aceto-nitrile disolvate and tetra-kis-(pyridine-4-thio-amide-?N)bis-(thio-cyanate-?N)nickel(II) methanol penta-solvate.

Project description:Reaction of Co(NCS)2 or Ni(NCS)2 with pyridine-4-thio-amide in different solvents led to the formation of two compounds with composition [Co(NCS)2(C2H3N)(C6H6N2S)3]·2CH3CN (1) and [Ni(NCS)2(C6H6N2S)4]·5CH3OH (2), respectively. The asymmetric unit of compound 1 consists of one cobalt(II) cation, two thio-cyanate anions, three pyridine-4-thio-amide ligands, one coordinating and two solvate aceto-nitrile mol-ecules. One of the two aceto-nitrile solvate mol-ecules is disordered over two sets of sites in a 0.62:0.38 ratio. The asymmetric unit of compound 2 comprises of one nickel(II) cation, two thio-cyanate anions, four N-bonding pyridine-4-thio-amide ligands and five methanol solvate mol-ecules. In compound 1, the cobalt(II) cations are octa-hedrally coordinated into discrete complexes by two terminal N-bonding thio-cyanate anions, the N atoms of three pyridine-4-thio-amide ligands and one aceto-nitrile mol-ecule. Additional aceto-nitrile solvate mol-ecules are located between the complexes,. The complexes and solvate mol-ecules are linked via inter-molecular hydrogen bonding into a three-dimensional framework. In compound 2, the nickel(II) cations are likewise octa-hedrally coordinated by two terminal N-bonded thio-cyanate anions and four N-bonding pyridine-4-thio-amide ligands into discrete complexes. From their arrangement cavities are formed, in which the methanol solvate mol-ecules are located. Again, the complexes and solvate mol-ecules are linked into a three-dimensional framework by inter-molecular hydrogen bonding.

Project description:In the title compound, [FeIr(C5H5)(C20H14N3)Cl3]·2CH3CN, the central Ir(III) atom is sixfold coordinated by three chloride ligands and three terpyridine N atoms in a slightly distorted octa-hedral fashion. The terpyridine ligand is functionalized at the 4'-position with a ferrocenyl group, the latter being in an eclipsed conformation. In the crystal, mol-ecules are stacked in rows parallel to [001], with the aceto-nitrile solvent mol-ecules situated between the rows. An extensive network of intra- and inter-molecular C-H⋯Cl inter-actions is present, stabilizing the three-dimensional structure.

Bis[bis-(penta-methyl-cyclo-penta-dien-yl)cobalt(III)] tetra-chlorido-cobaltate(II) di-chloro-methane disolvate.

Project description:The title compound, [Co(C10H15)2]2[CoCl4]·2CH2Cl2, was isolated as a dichloromethane solvate and was formed in the reaction between lithium penta-methyl-cyclo-penta-dienide and anyhydrous cobalt(II) chloride in tetra-hydro-furan. There are two deca-methyl-cobaltocenium cations, one tetrachloridocobaltate(II) anion and two di-chloro-methane solvent mol-ecules in the formula unit. There is a slight disorder of the di-chloro-methane solvent which was treated with a two-site model [occupancy rates = 0.765?(4) and 0.235?(4)]. The di-chloro-methane mol-ecules display significant C-H?Cl inter-actions with the tetrachloridocobaltate(II) dianion. The cobalt atom of the deca-methyl-cobaltocenium cation sits on a twofold rotation axis, with only one penta-methyl-cyclo-penta-diene ligand being unique and the second generated by symmetry. The cobalt atom of the [CoCl4](-2) ion sits on a special site with -4 symmetry, with one unique chloride ligand and the others generated by the fourfold inversion axis.

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.

Hexa-?2-chlorido-?4-oxido-tetra-kis[(morpholine-?N)copper(II)] methanol disolvate.

Project description:In the title solvate, [Cu4(?2-Cl)6(?4-O)(C4H9NO)4]·2CH3OH, each Cu(2+) ion in the tetra-nuclear complex has a trigonal-bipyramidal coordination arising from three bridging chloride ions in equatorial positions and the central ?4-O(2-) ion and morpholine N atom in axial positions. The morpholine rings adopt chair conformations, with the N-Cu bonds in equatorial orientations. In the crystal, the components are linked by N-H?O and O-H?O and O-H?Cl hydrogen bonds, which generate a three-dimensional network. One methanol mol-ecule is disordered over two sets of sites in a 0.642?(9):0.358?(9) ratio.
