Triazidotris[?-2-(2-pyridyl)ethanolato]dicobalt(II) acetonitrile monosolvate.

ABSTRACT: In the title compound, [Co(2)(C(7)H(8)NO)(3)(N(3))(3)]·CH(3)CN, the two Co(II) ions in the dinuclear complex have different coordination environments, both in a distorted octa-hedral geometry. One Co(II) atom is coordinated by three O atoms from the three 2-hy-droxy-ethyl-pyridine (HEP) bridging ligands, two N atoms from two HEP ligands and one azido ligand, while the other Co(II) atom is coordinated by the same three O atoms, one N atom from an HEP ligand and two azido ligands. Weak inter-molecular C-H?N hydrogen bonds link the dinuclear complexes into corrugated layers parallel to the bc plane. These layers are further packed with the formation of channels propagating in [010] and filled with the disordered [in a ratio 0.691?(13):0.309?(13)] acetonitrile solvate mol-ecules.

Bis(acetonitrile-?N)dichlorido(?-cyclo-octa-1,5-diene)ruthenium(II) acetonitrile monosolvate.

Project description:In the title Ru(II) complex, [RuCl(2)(C(8)H(12))(C(2)H(3)N)(2)]·CH(3)CN, the metal ion is coordinated to the centers of each of the double bonds of the cyclo-octa-diene ligand, to two chloride ions (in cis positions) and to two N-atom donors (from MeCN mol-ecules) that complete the coordination sphere for the neutral complex. The coordination about the Ru(II) atom can thus be considered to be octa-hedral with a slightly trigonal distortion. There is also one acetonitrile solvent mol-ecule per mol-ecule which is outside the coordination sphere of the ruthenium atom.

Tetra-kis(acetonitrile-?N)lithium hexa-fluoridophosphate acetonitrile monosolvate.

Project description:In the title compound, [Li(CH(3)CN)(4)]PF(6)·CH(3)CN, the asymmetric unit consists of three independent tetra-hedral [Li(CH(3)CN)(4)](+) cations, three uncoordinated PF(6) (-) anions and three uncoordinated CH(3)CN solvent mol-ecules.

Bromidotris(triphenyl-phosphane)silver acetonitrile monosolvate monohydrate.

Project description:In the title compound, [AgBr(C(18)H(15)P)(3)]·C(2)H(3)N·H(2)O, the coordination of the Ag atom is close to ideal tetra-hedral, with the three Ag-P bond lengths almost equal [2.5441 (10), 2.5523 (9) and 2.5647 (10) ° A] and the Ag-Br bond slightly longer [2.7242 (5) Å]. The coordination tetra-hedron is slightly flattened, the Ag atom is closer to the PPP plane; the P-Ag-P angles are wider than the Br-Ag-P angles. The voids in the crystal structure are filled with ordered acetonitrile solvent mol-ecules. The remaining electron density was inter-preted as a water mol-ecule, disordered over three alternative positions. Neither of the solvent mol-ecules is connected by any directional specific inter-actions with the complex.

Project description:In the title compound, [Cu(ClO(4))(C(2)H(3)N)(C(15)H(19)N(3)O)]ClO(4), the Cu(II) ion is coordinated by three N atoms and a hydroxyl-O atom of the tetra-dentate ligand, an O atom of a perchlorate ion and an N atom of an acetonitrile ligand giving a tetra-gonally distorted octa-hedral environment around the copper(II) atom. There is an offset inter-complex face-to-face π-π inter-action [centroid-centroid distance = 3.718 (2) Å] involving one of the pyridine rings of the ligand as well as an intra-complex O-H⋯O hydrogen-bonding inter-action between the coordinated hydroxyl group of the ligand and the perchlorate counter-ion.

Tris(5,6-dimethyl-1,10-phenanthroline-?(2)N,N')copper(II) bis-(hexa-fluorido-phosphate) acetonitrile monosolvate.

Project description:In the title compound, [Cu(C(14)H(12)N(2))(3)](PF(6))(2)·CH(3)CN, the [Cu(5,6-dmp)(3)](2+) cationic complex (5,6-dmp is 5,6-dimethyl-1,10-phenanthroline) is stabilized by two hexa-fluorido-phosphate anions and one acetonitrile solvent mol-ecule. The coordination geometry around the Cu(II) atom can be described as distorted elongated octa-hedral with R(out) = 2.277?(2)?Å, R(in) = 2.052?(2)?Å and a tetra-gonality of 0.9011, acquiring a 'static' stereochemistry. In the supra-molecular network, there are inter-molecular C-H?F and C-H?N inter-actions with R(3) (3)(16), R(2) (2)(7), R(1) (2)(4), R(3) (3)(16) and C(3) (2)(7) motifs that lead to an infinite three-dimensional network.

Bis(2,2'-bipyrimidine-?(2)N(1),N(1'))palladium(II) bis-(tetra-fluoro-borate) acetonitrile monosolvate.

Project description:The reaction of [Pd(MeCN)(4)](BF(4))(2) with 2,2'-bipyrimidine (bpm) in MeCN-CHCl(3) afforded the title compound, [Pd(C(8)H(6)N(4))(2)](BF(4))(2)·C(2)H(3)N. The asymmetric unit contains two half complexes, with the Pd(II) atoms both lying on a twofold axis. Each metal atom adopts a tetra-hedrally distorted square-planar geometry. In the crystal, [Pd(bpm)(2)] dications are linked by C-H?N hydrogen bonds, forming chains parallel to the b axis. The chains are further linked by C-H?F and C-H?N inter-actions involving the tetra-fluoro-borate anions and acetonitrile mol-ecules. In this way, each chain interacts with six surrounding chains to generate the observed three-dimensional structure.
