Synthesis and Crystal Structure of a new Cu2+complex

摘要：

　　(R,R)-N,N-di-(4-hydroxylbenzal)-1,2-cyclohexanediamine Schiff base(H2L) was synthesized and characterized by 1H NMR spectra,MS spectra and IR spectra.And the coordination reaction of H2L with chlorate of Cu(Ⅱ) was studied.The reaction of H2L with CuⅡ salt CuCl2generates a new compound,the title compound.The title compound was determined by IR spectra,elemental analysis and single-crystal X-ray diffraction.The title compound belongs to the monoclinic system,space group P2(1),with α =6.6393(6)(A),b =24.735(2)(A),c =8.1128(7)(A),α=90.00 °,β=110.1670(10) °,γ=90.00 °,Z=2,V=1250.60(19) (A),Dc=1.382 mg.m-3,μ=1.020mm-1,F (000) =554,R=0.0351 and wR=0.0887.There are five coordination sites around Cu2+ of the title compound,which are respectively occupied by one oxygen atom from one H2O molecule and four nitrogen atoms from two 1,2-cyclohexanediamine molecules.The Cu atom and four chelating nitrogen atoms are coplanar.There exist rich intra-molecular H-bond and intermolecular H-bond,which result in a three dimensional net.
