N，N‘-二(3-吡啶基)己二胺(L)与相应的银(I)盐反应，得到了配合物{[Ag(L)](Pf_6)·2CH_3CN}∞，1，{[Ag(L)](BF_4)·CH_3CN}∞，2，{[Ag(L)](NO_3)·CH_3CN}∞，3，{[Ag(L)](Pf_6)·4DMF}∞，4，{[Ag(L)](BF_4)·4DMF}∞，5，{[Ag(L)](CF3SO3)·dmf}∞，6，{[Ag(L)](ClO4)·CH3CN}∞，7，{[Ag(L)](ClO4)}∞，8，[Ag2(L)2](p-Tso)2·2CH3CN(p-Tso=对甲苯磺酸)，9，[Ag(L)(p-Tso)]∞，10.配合物1形成一维(一维)凹凸链，配合物2，3，6，和7显示了由Ag-Ag和π-π相互作用支撑的一维锯齿链聚合物对，而配合物4、5和8采用锯齿链。配合物9形成零维(0D)双核金属环，配合物10分别形成具有{4，82}拓扑的二维折叠网格。这些配合物中的L配体具有不同的配体构象，这些构象受到反阴离子和溶剂的影响，导致了不同的结构类型。可逆的晶体到晶体的转变被认为是可逆的。
The reactions of N,N′-di(3-pyridyl)adipoamide (L) with the corresponding silver(I) salts afforded the complexes {[Ag(L)](PF6)·2CH3CN}∞, 1, {[Ag(L)](BF4)·CH3CN}∞, 2, {[Ag(L)](NO3)·CH3CN}∞, 3, {[Ag(L)](PF6)·4DMF}∞, 4, {[Ag(L)](BF4)·4DMF}∞, 5, {[Ag(L)](CF3SO3)·DMF}∞, 6, {[Ag(L)](ClO4)·CH3CN}∞, 7, {[Ag(L)](ClO4)}∞,8, [Ag2(L)2](p-TsO)2·2CH3CN (p-TsO = p-toluenesulfonate), 9, and [Ag(L)(p-TsO)]∞, 10. Complex 1 forms a one-dimensional (1D) concavo-convex chain, and complexes 2, 3, 6, and 7 show 1D polymeric pairs of zigzag chains supported by the Ag---Ag and π–π interactions, whereas complexes 4, 5, and 8 adopt zigzag chains. Complex 9 forms a zero-dimensional (0D) dinuclear metallocycle, and complex 10 shows a two-dimensional (2D) pleated grid with a {4,82} topology, respectively. The L ligands in these complexes adopt various ligand conformations, which are subjected to the changes of the counteranions and solvents, resulting in the different structural types. Reversible crystal-to-crystal transformation was o...
