Condensation of 2-pyridinecarboxaldehyde with six primary amines containing aliphatic groups gave the corresponding pyridinecarboxaldimines (N-N′R). Addition of these ligands to [PtCl2(coe)]2 (coe = cis-cyclooctene) gave complexes of the type cis-PtCl2(N-N′R) (1: R = propyl, 2: R = hexyl, 3: R = octyl, 4: R = nonyl, 5: R = hexadecyl, and 6: R = octadecyl) in moderate yields. The molecular structure
2-吡啶甲醛与六个含有脂肪族基团的伯胺缩合得到相应的吡啶甲二亚胺(NN'R)。将这些配体添加到 [PtCl2(coe)]2 (coe = 顺式环辛烯) 中得到顺式 PtCl2(NN'R) 类型的配合物 (1: R = 丙基, 2: R = 己基, 3: R = 辛基, 4: R = 壬基, 5: R = 十六烷基, 和 6: R = 十八烷基),产率中等。己基衍生物 (2) 的分子结构已通过 X 射线衍射研究证实。2 的晶体为三斜晶系,a = 8.6858(19) A,b = 8.7567(19) A,c = 9.5080(19) A,α = 76.546(3)°,β = 87.151(3)°,γ = 78.586 (3)° 在空间群 P1 中。所有铂络合物都显示出相当大的抗菌和抗分枝杆菌特性。
