Crystal structure of cis-tetra-aqua-dichlorido-cobalt(II) sulfolane disolvate.

ABSTRACT: In the title compound, [CoCl2(H2O)4]·2C4H8SO2, the Co(II) cation is located on the twofold rotation axis and is coordinated by four water mol-ecules and two adjacent chloride ligands in a slightly distorted octa-hedral coordination environment. The cisoid angles are in the range 83.27?(5)-99.66?(2)°. The three transoid angles deviate significantly from the ideal linear angle. The crystal packing can be described as a linear arrangement of complex units along c formed by bifurcated O-H?Cl hydrogen bonds between two water mol-ecules from one complex unit towards one chloride ligand of the neighbouring complex. Two solvent mol-ecules per complex are attached to this infinite chain via O-H?O hydrogen bonds in which water mol-ecules act as the hydrogen-bond donor and sulfolane O atoms as the hydrogen-bond acceptor sites.

Crystal structure of poly[[di-aqua-tetra-μ2-cyanido-iron(II)platinum(II)] acetone disolvate].

Project description:In the title polymeric complex, {[FePt(CN)4(H2O)2]·2C3H6O} n , the FeII cation has an octa-hedral [FeN4O2] geometry being coordinated by two water mol-ecules and four cyanide anions. The Pt cation is located on an inversion centre and has a square-planar coordination environment formed by four cyanide groups. The tetra-cyano-platinate anions bridge the FeII cations to form infinite two-dimensional layers that propagate in the bc plane. Two guest mol-ecules of acetone per FeII are located between the layers. These guest acetone mol-ecules inter-act with the coordinated water mol-ecules by O-H⋯O hydrogen bonds.

Synthesis, crystal structure and Hirshfeld surface analysis of tetra-aqua-bis-(isonicotinamide-κN1)cobalt(II) fumarate.

Project description:The reaction of cobalt(II) with fumaric acid (H2fum) and isonicotinamide in a basic solution produces the title salt, [Co(C6H6N2O)2(H2O)4](C4H2O4). In the complex cation, the CoII atom, located on an inversion centre, is coordinated by two isonicotinamide and four water mol-ecules in a distorted N2O4 octa-hedral geometry. The fumarate anion is located on another inversion centre and is linked to neighbouring complex cations via O-H⋯O and N-H⋯O hydrogen bonds and weak C-H⋯O hydrogen bonds. In the crystal, the complex cations are further linked by O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular architectecture. Hirshfeld surface analyses (dnorm surfaces and two-dimensional fingerprint plots) for the title compound are presented and discussed.

Crystal structure of the tetra-aqua-bis-(thio-cyanato-?N)cobalt(II)-caffeine-water (1/2/4) co-crystal.

Project description:In the structure of the title compound [systematic name: tetra-aqua-bis-(thio-cyanato-?N)cobalt(II)-1,3,7-trimethyl-1,2,3,6-tetra-hydro-7H-purine-2,6-dione-water (1/2/4)], [Co(NCS)2(H2O)4]·2C8H10N4O2·4H2O, the cobalt(II) cation lies on an inversion centre and is coordinated in a slightly distorted octa-hedral geometry by the oxygen atoms of four water mol-ecules and two N atoms of two trans-arranged thio-cyanate anions. In the crystal, the complex mol-ecules inter-act with the caffeine mol-ecules through O-H?N, O-H?O and C-H?S hydrogen bonds and ?-? inter-actions [centroid-to-centroid distance = 3.4715?(5)?Å], forming layers parallel to the ab plane, which are further connected into a three-dimensional network by O-H?O and O-H?S hydrogen bonds involving the non-coordinating water mol-ecules.

catena-Poly[[[tetra-aqua-cobalt(II)]-?-4,4'-bipyridine-?N:N'] bis-(perchlorate) 4,4'-bipyridine disolvate dihydrate].

Project description:In the title compound, {[Co(C(10)H(8)N(2))(H(2)O)(4)](ClO(4))(2)·2C(10)H(8)N(2)·2H(2)O}(n), slightly distorted octa-hedrally coordinated Co(II) ions situated on inversion centers are linked into polycationic chains through 4,4'-bipyridine tethering ligands. These are connected into supra-molecular layers by hydrogen bonding involving aqua ligands, perchlorate anions and uncoordinated water mol-ecules. A twofold inter-penetrated primitive cubic supra-molecular network is formed by the inter-action of pseudo-layers by hydrogen bonding between aqua ligands and unligated 4,4'-bipyridine mol-ecules.
