Synthesis and crystal structure of a new mononuclear copper complex

A new kind of Cu (II) complex [Cu(tpmb)(2)Cl-2].CH3OH.H2O (tpmb = 1,3,5-tri(2-pyrimidinyl)sulfanyhnethyl-2,4,6-trimelhylbenzene) was synthesized, and its structure has been determined by X-ray single-crystal diffraction. It crystallizes in the triclinic, space group P (1) over bar with a = 8.8397(2), b = 13.327(3), c = 13.926(3) Angstrom, alpha = 63.27(3), beta = 86.96(3), gamma = 80.68(3)degrees, V = 1445.6(5) Angstrom(3), C49H51Cl2CuN12O2S6, M-r = 1166.82, Z = 1, F(000) = 604, D-c = 1.340 g/cm(3), mu = 0.735 mm(-1), R = 0.0545 and wR = 0.1575 for 4521 observed reflections (I > 2sigma(I)). X-ray analysis reveals that the Cu (II) ion is coordinated by two Cl- anions and two nitrogen atoms from different pyrimidine groups, forming a square structure.
