【摘要】 报道了混合配合物[Cu0.5Mn0.5(phen)2Cl]OH·3H2O的合成、表征和晶体结构分析.该晶体属单斜晶系,具有C2/c空间群,a=2.3321(5),b=3.0295(6),c=0.7492(1)nm,β=97.85(3)°.V=5.244(3)nm,Z=8,Dc=1.516g/cm3,F(000)=1244,R=0.066,Rw=0.068.该化合物含[Cu(phen)2Cl]+和[Mn(phen)2Cl]+阳离子,它们以金属离子各50%的几率在晶胞中无序排列.晶胞中分两层排布8个这样的阳离子单元;水分子和OH-离子分布其中.

【Abstract】 Copper(Ⅱ) and manganese(Ⅱ) ions are very important in many biological systems, such as photosynthesis system Ⅱ and superoxide dismutase. The synthesis of Cu(Ⅱ)and Mn(Ⅱ) complexes is a hot-spot not only in bioinorganic chemistry but also in molecular magnetism research. Herein, we report a new mixed complex [Cu0.5Mn0.5 (phen)2Cl] OH·3H2O. It is synthesized and characterized by elemental analysis,IR and UV-Vis spectroscopy.The structure of the single crystal is determined by X-ray diffraction. It belongs to the monoclinic system,space group C2/c,with a =2.3321(5),6 = 3.0295(6),c = 0.7492(1)nm,β = 97.85(3)°. V = 5.244 (3)nm3,Z = 8,Dm = 1.425g/cm3,Dc = 1.333g/cm3, F(000) = 2168, R = 0.066, RW = 0.068. Both metal ions lie in tetragonal pyramidal environment.
