Synthesis, crystal structure and thermal stability of complex [Cu(C 14H10O4)(C12H8N 2)2]·2H2O

The title complex has been synthesized with 2,2.-biphenyl dicarboxylic acid and 1,10-phenanthroline (phen) in the solvent mixture of water and methanol. It crystallizes (C38H28CuN4O6, M r = 700.1) in triclinic, space group P1 with a = 1.0868(2), b = 1.2175(2), c = 1.6206(3) nm, α = 110.161(2), β = 102.605(3), γ = 93.667(2)°, V = 1941.6(6) nm3, Dc = 1.198 g/cm 3, Z = 2, F(000) = 722, R = 0.0558 and wR = 0.1208. The crystal structure shows that the copper atom is coordinated with one oxygen atom from 2,2.-bphenyl dicarboxylic acid molecule and four nitrogen atoms from two 1,10-phenanthroline molecules, forming a distorted square-pyramidal coordination. The TG analysis shows that the title complex is stable under 160.0 °C.
