Reaction of bis(4,6-dimethyl-2-pyrimidinethiolato)methane(bpytm)with CuCl_2·4H_2O in a mixed methanol/dichloromethane solution gave a one-dimensional coordina-tion polymer[CuCl_2(μ-bpytm)]_n which was characterized by single-crystal X-ray diffraction.It crystallizes in monoclinic,space group P2_1/c with a=16.9433(5),b=13.6986(4),c=7.8434(2)(A),β=100.371(2)°,ν=1790.71(9)(A)~3,Z=4,M_r=426.86,D_c=1.583 g/cm~3,μ(MoKa)=1.751 mm~(-1),F(000)=868,S=1.025,the final R=0.0399 and wR=0.0924 for 2538 observed reflections with I ＞2 σ(1)and 206 variables.The neutral coordination polymer is constructed by the bidentate thioether ligands to link adjacent copper atoms.Each copper atom is bridged by two adjacent nitrogen atoms of bpytm ligands and terminally bonded by two chloride atoms to form a squareplanar coordination geometry.The average Cu-N and Cu-Cl bond lengths are 2.025(2)and 2.234(1)(A),respectively.
