摘　　要：以硫酸锌、对氯苯甲酸、1,10-邻菲啰啉为原料在乙腈和水的混合溶剂中(乙腈与水的体积比为5∶1)合成一种双锌配合物[Zn_(2)(L)_(4)(phen)_(2)]·H_(2)O,并对其进行晶体结构测定。测定结果表明:该配合物晶体属单斜晶系,空间群C2/c,晶胞参数:a=2.3403(2)nm,b=1.56059(15)nm,c=1.56072(15)nm,β=121.040(10)°,M_(r)=1131.40,V=4.8839(8)nm^(3),Z=4,D_(c)=1.510 g·cm^(-3),F(000)=2256,μ(Mo K_(α))=0.80,最终偏离因子GOOF值为1.033,R_(1)=0.0373,wR_(2)=0.0543.中心锌离子由6个原子配位形成变形的八面体结构,配合物在429 K下具有热稳定性,在419 nm处显示较强的荧光吸收峰。A new dinuclear zinc(II)complex Zn_(2)(L)_(4)(phen)_(2)·H_(2)O was synthesized with zinc sulfate,p-chlorobenzoic acid(HL)and 1,10-phenanthroline(phen)in the mixed acetonitrile/water(5∶1 in volume)mixtures.Its crystalline pattern belongs to the monoclinic space group C2/c,with a=2.3403(2)nm,b=1.56059(15)nm,c=1.56072(15)nm,β=121.040(10)°,M_(r)=1131.40,V=4.8839(8)nm3,Z=4,D_(c)=1.510 g·cm^(-3),F(000)=2256,andμ(Mo K_(α))=0.80.The final GOOF is 1.033,R_(1) is 0.0373,and wR_(2) is 0.0543.The Zn(II)ion is six-coordinated to give a distorted octahedral geometry.The complex remains thermally stable before 429 K and holds a strong fluorescence at around 419 nm.
