Structure and Properties of A dimer Complex:Co(Hdmg)2(Him)2·(ClO4)

摘要：

　　A new complex crystal Co(Hdmg)2(Him)2·(ClO4) (H2dmg =dimethylglyoxime,Him =imidazole) had been synthesised in aqueous solution and was characterized by X-ray diffraction and IR spectrum.The complex crystallizes in triclinic space group with cell constants a=20.868(7)(A),b =11.408(4)(A),c =15.816(4)(A),α =90.00°,β =116.97(2)°,γ =90.00°,V =3355.8(17)(a)3,Z =4,F (000)=1732.The coordination environment of cobalt atom is a slightly distorted octahedron.The four equatorial donors are four nitrogen atoms from two bidentate chelate Hdmg anion ligands.The apex points are occupied by two nitrogen atoms from Him ligands.The CoN(Him) distance is 1.930(A),and the Co-N(dmg) distances are varying in the range from 1.886(A) to 1.993(A) which are in agreement with corresponding reported in a number of other structurally related copper(Ⅱ) complexes.
