ABSTRACT: In the title compound, [Cu(C(10)H(8)N(3)O(2))(2)]·4H(2)O, the Cu(II) ion has a distorted octa-hedral coordination formed by four O [Cu-O = 2.051?(3)-2.083?(4)?Å] and two N [Cu-N = 1.985?(4) and 1.996?(4)?Å] atoms from two tridentate bis-(1-oxo-2-pyrid-yl)aminate ligands. In the two ligands, the pyridyl rings form dihedral angles of 21.0?(1) and 15.5?(1)°. The crystal packing exhibits an extensive network of O-H?O hydrogen bonds and ?-? inter-actions proved by short distances of 3.650?(1) and 3.732?(2)?Å between the centroids of pyridyl rings of neighbouring mol-ecules.

Project description:The title compound, [Zn(C(6)H(4)N(5))(2)(H(2)O)(4)]·4H(2)O, was synthesized by the hydro-thermal reaction of Zn(CH(3)COO)(2)·2H(2)O with 3-(2H-tetra-zol-5-yl)pyridine.

Tetra-?-benzoato-bis-{[trans-1-(2-pyrid-yl)-2-(4-pyrid-yl)ethyl-ene]zinc(II)}.

Project description:The paddle-wheel-type centrosymmetric dinuclear title complex, [Zn(2)(C(7)H(5)O(2))(4)(C(12)H(10)N(2))(2)], contains four bridging benzoate groups and two terminal trans-1-(2-pyrid-yl)-2-(4-pyrid-yl)ethyl-ene (L) ligands.

The Zn(II) atom is 0.372?Å out of the plane of the four coordinating O atoms.

Bis{2-[2,5-bis-(pyridin-2-yl)-1H-imidazol-4-yl]pyridinium} tetra-cyanidoplatinate(II) tetra-hydrate.

Project description:The asymmetric unit of the title hydrated complex salt, (C18H14N5)2[Pt(CN)4]·4H2O, consists of one 2-[2,5-bis-(pyridin-2-yl)-1H-imidazol-4-yl]pyridinium cation, half a tetra-cyanidoplatinate(II) dianion, which is located about a crystallographic inversion center, and two water mol-ecules of crystallization. The Pt(II) atom has a square-planar coordination environment, with Pt-CCN distances of 1.992 (4) and 2.000 (4) Å. In the cation, there is an N-H⋯N hydrogen bond linking adjacent pyridinium and pyridine rings in positions 4 and 5. Despite this, the organic component is non-planar, as shown by the dihedral angles of 10.3 (2), 6.60 (19) and 15.66 (18)° between the planes of the central imidazole ring and the pyridine/pyridinium substituents in the 2-, 4- and 5-positions. In the crystal, cations and anions are linked via O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds, forming a three-dimensional network. Additional π-π, C-H⋯O and C-H⋯N contacts provide stabilization to the crystal lattice.
