It is worthy of mentioning that complex 21 is the first (3, 4)-connected self-penetrating 3D polymer; complex 22 is the first two-fold interpenetrating trinodal 4-connected network with (64·82)(63·83)2(65·8) topology; complexes 23-27 all show three-fold interpenetrating networks, containing the rare (3, 4)-connected (63)2(64·8·10)3 net and the common diamond nets as well as α-Po nets.

值得注意的是，配合物21是第一个(3， 4)-连接的自穿插网格；配合物22是第一个二重穿插的三节点4-连接的(64.82)(63.83)2(65.8)拓扑网格；配合物23-27呈现三重穿插的网络结构，包括少见的(3， 4)-连接(63)2(64.8.10)3拓扑网格以及常见的金刚石网格和α-Po立方格子。
