Synthesis and crystal structure of Zn(Ⅱ) complex of 1-phenyl-3-methyl-4-benzoyl-pyrazol-5-one

在乙醇溶液中,以1-苯基-3-甲基-4-苯甲酰基-5-吡唑啉酮(HPMBP)为配体,合成了标题配合物[Zn(PMBP)2(EtOH)2],并表征了其晶体结构.结果表明该配合物属单斜晶系,空间群为P2(1)/n,晶胞参数为:a=1.487 3(2)nm,b=1.462 6(2)nm,c=1.715 3(3)nm,α=90°,β=105.573(2)°,γ=90.°Z=4,Dc=1.316 Mg/m3,μ=0.734 mm-1,F(000)=1 488.配合物中的锌离子与2个PMBP-中的4个氧原子以及2个醇分子中的氧原子配位,而形成六配位的变形八面体.

The title complex was synthesized by using 1-phenyl-3-methyl-4-benzoyl-pyrazol-5-one（HPMBP） as ligand in ethanol solution and its crystal structure was characterized.The results showed that the title complex belongs to monoclinic system with P2（1）/n space group and cell parameters are： a = 1.487 3（2） nm,b = 1.462 6（2） nm,c = 1.715 3（3） nm,α = 90°,β = 105.573（2）°,γ = 90°.Z = 4,Dc = 1.316 Mg/m3,μ = 0.734 mm-1,F（000） = 1 488.In the crystal Zn（Ⅱ） ion is coordinated by four oxygen atoms from two PMBP-ligands and two oxygen atoms from solvent ethanol molecules to form a distorted octahedral geometry.
