摘要
报道了由CuI和1,4-双(二苯基膦)丁烷(dppb)合成的双核配合物Cu2(μ-dppb)2(μ-I)2,并测定了其晶体结构.该晶体属正交晶系,空间群为pbca,a=1.8206(4)nm,b=1.5219(3)nm,c=1.8280(4)nm,V=5.0650(19)nm3,Z=4,R=0.0443,wR=0.0832,S=1.086.该化合物是一个双核结构,对称中心位于两个铜原子连线的中点处.其结构特点为一个双环骨架:外环由Cu-dppb-Cu-dppb组成一个十四元环,内环由两个Cu+和两个I-离子组成一个四元环,两环基本相互垂直.
The reaction of CuI with 1,4-di (diphenylphosphine) butane ( dppb ) in isopropanol-acrtonitrile mixedsolvents under solvothermal conditions resulted in a dimeric lphosphine) butane). This compound was characterized by complex Cu2 (μ-dppb) 2 (μ-I ) 2 ( dppb = 1,4-di ( dipheny- IR, elemental analysis and single-crystal X-ray crystallography. It crystallizes in the orthorhombic space group pbca with a = 1. 820 6(4)nm,b = 1. 521 9(3)nm,c = 1. 828 0 (4) nm, V = 5. 065 0 ( 19 ) nm^3, Z = 4, R = 0. 044 3, wR = 0. 083 2, S = 1. 086. It has a eentrosymmetriedimerie structure formed by a Cu2I2 four-membered rhomb and a fourteen-membered Cu-dppb-Cu-dppb ring.
