The preparations of complexes of rhodium(III) with the cyclic tetra-amines C-rac- and C-meso-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetra-azacyclotetradecane are reported. For both isomers, trans-diacido-derivatives were prepared. For the C-rac-isomer a series of derivatives with the amine in folded (a,b,c,d) co-ordination, with a chelate or cis-unidentate ligands in the two additional co-ordination sites
铑(III)与环状四胺C-rac-和C-meso -5,5,7,12,12,14-六甲基-1,4,8,11-四氮杂环十四烷的配合物的制备为报告。对于两种异构体,制备了反式-二酸衍生物。对于C-rac-异构体,还制备了一系列胺在折叠(a,b,c,d)配位的衍生物,在两个另外的配位位点具有螯合物或顺式-不相同的配体。据报道,由四个手性氮中心产生的配合物的构型异构现象。
