Özet

The synthesis and crystal structure of a new Ni(II) complex of stoichiometry [Ni(phen)(2)(H2O)(2)](H(2)Or)(2) center dot 2H(2)O, where phen is phenanthroline and H(2)Or is oratate monoanion, are reported. The complex [Ni(phen)(2)(H2O)(2)](H(2)Or)(2) center dot 2H(2)O crystallizes in the monoclinic system with space group C2/c and cell parameters a = 16.1661(8) angstrom, b = 12.5669(7) angstrom and c = 16.4752(7) angstrom. The coordination around Ni(II) is a distorted octahedron with two phen ligands perpendicular to each other and two aqua ligands in cis- position. Orotate ions locate themselves out of the coordination sphere and bridge the [Ni(phen)(2)(H2O)(2)](2+) moieties through hydogen bonding with aqua ligands. The FT-IR spectrum of the complex and thermal decomposition behaviour are also briefly discussed.
