system is amenability to single-crystal x-ray structure determination and this is demonstrated with an x-ray structure of a copper(II) complex. Crystal data for CuC/sub 74/H/sub 66/N/sub 12/O/sub 3/1.5 (diethyl ether) toluene are the following: monoclinic, C2/c, a = 31.240 (4) A, b = 16.769 (5) A, c = 35.199 (4) A, ..beta.. = 121.4 (1)/sup 0/; R = 0.0826, R/sub W/ = 0.0826.

报道了一些新的双核四芳基卟啉配体的合成和表征。可能最有用的例子是..cap alpha..,..cap alpha..,5-15-bis(N-(2-methylbenzimidazolyl) acetamidophenyl)-..cap alpha..,..cap alpha.., 10-20-双(新戊酰胺苯基)卟吩(8)。配体有两个附加的苯并咪唑臂,用于螯合卟啉正上方的第二种金属。从 ..cap alpha..、..cap alpha..、..cap alpha.. 获得 5,15(即反式)和 5,10(即顺式)双附加配体的合成方法。 , ..cap alpha..,5,10,15,20 四官能化的起始材料进行了详细描述。配体系统的一个关键设计特征是适用于单晶 X 射线结构测定,这可以通过铜 (II) 配合物的 X 射线结构来证明。CuC/sub 74/H/sub 66/N/sub 12/O/sub
