摘　　要：The structures of [MCl2(C6H4N3CH2COPh)2] [M=Zn(II) (1), Co(II) (2)] have been determined by X-ray crys-tallography. They were characterized by elemental analysis, IR spectrum, electronic spectrum and thermogravimet-ric-differential thermal analysis. They all crystallize in the triclinic system, space group P? with lattice parameters a=0.9449(2) nm, b=1.1291(2) nm, c=1.3637(3) nm, a=111.70(3)o, b=94.33(3)o, =90.97(3), Z=2 for com-pound 1; a=0.9437(2) nm, b=1.1277(2) nm, c=1.3650(3) nm, =111.76(3)o, =94.50(3)o, =90.80(3)o, Z=2 for compound 2. The metal ions are all coordinated by two Cl- anions and two nitrogen atoms of 1-benzoylmethyl-benzotriazole ligands, forming the distorted tetrahedral geometry. The ZnCl and ZnN bond lengths are 0.2209(2), 0.2210(2) nm and 0.2059(4), 0.2067(4) nm, respectively. The CoCl and CoN bond lengths are 0.2215(2), 0.2222(2) nm and 0.2028(5), 0.2045(5) nm, respectively. The thermogravimetric (TG) data indicate that they are nearly similar in TG curve, and there are not structural transitions in the two compounds. They all have a high thermal stability. But, there is little difference in DTG (differential thermogravimetric) curves of those two compounds. Elemental analysis, electronic and IR spectra are in agreement with the structural data.The structures of [MCl2(C6H4N3CH2COPh)2] [M=Zn(II) (1), Co(II) (2)] have been determined by X-ray crys-tallography.
