The title complex, [Co(2)Cl(4)(C(10)H(8)N(2))(2)(H(2)O)(2)], is composed of two Co(II) atoms, each hexa-coordinated by three Cl atoms, one 2,2'-bipyridine (bpy) ligand and one water mol-ecule in a distorted octa-hedral geometry. Neighboring Co(II) atoms are linked together by two Cl bridges, forming a dinuclear Co(II) complex with inversion symmetry. There(More)
The crystal structure of the title compound, [Co(3)(C(5)H(9)O(2))(6)O(CH(4)O)(3)]Cl, consists of trinuclear Co(III) complex cations and chloride anions. The Co(III) cation has site symmetry m, and is coordinated by four oxygen atoms from four bridging pivalate groups, one central O anion and a methanol oxygen atom, forming a distorted octa-hedral geometry.(More)
In the title complex, [Cu(C(14)H(13)N(2)O(2))(2)], the Cu(II) ion is located on a crystallographic inversion center. The complex thus adopts a square-planar trans-[CuN(2)O(2)] coordination geometry, with the Cu(II) ion coordinated by two 2-meth-oxy-6-(3-pyridylmethyl-imino-meth-yl)phenolate (Schiff base) ligands. The aryl and pyridyl rings in the Schiff(More)
In the title mononuclear complex, [Cu(C(13)H(10)ClN(2)O)(H(2)O)]-NO(3)·H(2)O, the Cu(II) atom is four-coordinated by two N atoms and one O atom of the tridentate Schiff base ligand and one O atom from the coordinated water mol-ecule in a slightly distorted square-planar configuration. The nitrate ion inter-acts with the copper center [Cu1⋯O3 = 2.579 (4) Å].(More)
In the risperidone cation of the title compound, C(23)H(28)FN(4)O(2) (+)·NO(3) (-), the piperidine ring adopts a chair conformation and the tetra-hydro-pyridine ring is disordered over two orientations in a 0.620 (11):0.380 (11) ratio. N-H⋯O, C-H⋯O and C-H⋯F hydrogen bonds are present in the crystal structure.
In the title compound, [Co(C(5)H(9)O(2))(2)(C(12)H(8)N(2))(H(2)O)], the Co(II) atom is coordinated in a distorted octahedral environment by three carboxyl O atoms of two trimethyl-acetate ligands, one aqua O atom and two N atoms from 1,10-phen-anthroline. The crystal structure is stabilized by O-H⋯O hydrogen bonds and π-π stacking inter-actions(More)
The crystal structure of the title compound, [Zn(C(9)H(7)N(2)O(2))(2)(H(2)O)]·H(2)O, involves discrete mononuclear complex mol-ecules. The special positions on the rotation twofold axis are occupied by Zn(II) and O atoms of the coordinated and uncoordinated water mol-ecules. The coordination around the Zn(II) atom can be described as transitional from(More)
