dithioether ligand bis(4-pyridylthio)methane (4bpytm) with silver(I) salts afforded four complexes with 1:1 stoichiometries, namely [Ag(4bpytm)](NO3) (1), [Ag(4bpytm)](ClO4) (2) and [Ag(4bpytm)](ClO4) ½CH2Cl2 ½dmf (2·Solv), [Ag(CH3COO)(4bpytm)]·H2O (3) and [Ag(CF3COO)(4bpytm)] (4). X-ray structural analysis of these complexes showed that one-dimensional structures are obtained for 1, 2·Solv and 4 whereas
扭曲的吡啶基二硫醚配体双(4-吡啶硫基)甲烷(4bpytm)与银(I)盐的反应提供了化学计量比为1:1的四种配合物,即[Ag(4bpytm)](NO 3)(1),[Ag( 4bpytm)](CLO 4)(2)和[Ag(上4bpytm)](CLO 4)½CH 2氯2 ½dmf(2 · SOLV)和[Ag(CH 3 COO)(4bpytm)]·H 2 O(3)和[Ag(CF 3 COO)(4bpytm)](4)。这些复合物的X-射线结构分析显示,获得一维结构1,2 ·Solv和4,而在3中形成一个二维网络。配体4bpytm在所有情况下均作为N,N′-双(单齿)桥连系统,除了在3中,其中利用其两个吡啶氮原子和硫原子以三齿方式起作用的配体获得了空前的配位模式。配位聚合物是通过辅助触头组装:银...银在4,银...
