Synthesis and crystal structure of the new complex [Cd(H2O)2(phen)2] (PA)2

The new compound was prepared by the reaction of Cd(ClO4)(2) . 6H(2)O, 1, 10-phenanthroline (phen)and picric acid (HPA) (ratio 1: 3: 2) in methanol-aqueous solution refluxing for 4 hours. The crystals used for X-ray analysis was obtained by slow evaporation of the solution at room temperature. The crystal compound is in triclinic with space group P (1) over bar with a = 1.1363 (4) mu, b = 1.2593 (2) rim, c = 1.3972 (4) nm, alpha = 93.97 (2) Angstrom, beta = 100.84 (3) Angstrom, gamma = 106.29 (2) Angstrom, Z = 2, V = 1.8690 (9) nm(3), D-c = 1.715g . cm(-3), mu(MoKalpha) = 0.677 mm(-1), F(000) = 972, R = 0.0907, wR = 0.2240. In the complex, the Cd (II) cation is octahedrally coordinated to two 1, 10-phenanthroline ligands and two water molecules in cis disposition. As outer sphere, picrate anions are combined with inner by hydrogen bond and static electricity interaction.
