摘要

A series of 2, 6-pyrido crown ethers with ring sizes of 15-33 ring atoms has been synthesized. Their complexation with guanidinium salts has been studied by using two phase extraction experiments. The crystal and molecular structures of 2, 6-pyrido-27-crown- 9-guanidinium perchlorate (l: l), 2, 6-pyrido-30-crown-lGguanidinium perchlorate (l: l), 2, 6- pyrido-27-crown-9-guanidinium thiocyanate-ethanol (2: 3: 1), 2, 6-pyrido-27-crown-9- ...
