A novel ternary complex of [NiL1L2·2H2O]·NO3·H2O （L1 = 2-hydroxyl-1,10-phenanthroline （HOphen）, L2 = 2-hydroxynicotinic acid （H2nicO）） was synthesized, and its crystal structure was determined by ...A novel ternary complex of [NiL1L2·2H2O]·NO3·H2O （L1 = 2-hydroxyl-1,10-phenanthroline （HOphen）, L2 = 2-hydroxynicotinic acid （H2nicO）） was synthesized, and its crystal structure was determined by X-ray diffraction and further characterized by infrared and elementary analysis. The title complex （C18H18NiN4O10, Mr = 509.07） belongs to the triclinic system, space group P1^- with a = 712490（7）, b = 11.0164（10）, c = 13.3864（13）A, α = 91.6040（10）,β= 98.8620（10）, γ= 107.1140（10）°, V= 1006.43（17）A^3, Z = 2, Dc = 1.680 g/cm^3,μ= 1.032 mm^-1, F（000） = 524, the final R = 0.0461 and wR= 0.1238. In the complex, the Ni（H） ion is six-coordinated to assume a distorted octahedral geometry, and a 3D supramolecular network comes into being via weak intermolecular interactions of X-O--.H （X = N, O）.展开更多

In the structure of [Ni( ì3-OH)( ì3-ClO4)(H2O)]n, the local coordinating geometry around Ni center displays a distorted octahedron in which one coordination site of each metal atom was occupied by a water molecule. Each perchlorate anion and hydroxyl group acts as a tridentate bridging spacer to bind three Ni atoms, thus resulting in the formation of two-dimensional layered network. CSD: 414263.展开更多
