Abstract

A robust heteromeric hydrogen-bonded synthon [R2(2) (9)-Id] is exploited to drive the modular self-assembly of four coordination complexes [M(H2biim)2(OH2)2]2+ (M = Co2+, Ni2+) and carboxylate counterions. This strategy allowed us to build molecular architectures of 0-, 1-, and 2-dimensions. A hydrogen-bonded 2D-network with cavities has been designed, which maintains its striking integrity after reversible water desorption-resorption processes.

摘要

一种强大的异质氢键合成子[R2(2) (9)-Id]被用于驱动四种配位络合物[M(H2biim)2(OH2)2]2+（M = Co2+，Ni2+）与羧酸盐抗衡离子的模块化自组装。这一策略使我们能够构建零维、一维和二维的分子结构。设计了一种带有空腔的氢键二维网络，该网络在可逆的水脱附-再吸附过程后仍保持其显著的完整性。
