Three cyano bridged hetero-metallic complexes of general formula, [Cu(NH3)2(μ-ampy)M(μ-CN)2(CN)2]n [ampy=4-aminomethylpyridine, M=Ni(II) (1), Pd(II) (2) and Pt(II) (3)] have been synthesized and characterized by vibrational (FT-IR and Raman) spectroscopy, single crystal X-ray diffraction, thermal analyses and elemental analyses. The complexes crystallize in triclinic system with space group P-1. In all complexes, M(II) ions are coordinated by four cyano ligands, and four N atoms in the equatorial plane around the Cu atom form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by the cyanide N atoms in the axial positions. In one-dimensional structures of all the complexes, Cu(ampy) cations and M(CN)4 anions are linked via bridging cyano ligands. The adjacent one-dimensional structures form a 2D network to connect by the μ-ampy bridging ligands. The 2D layers are further linked by metal⋯π and hydrogen bonding interactions to generate a three dimensional network.
三种氰桥异金属配合物，通式为[Cu(NH3)2(μ-ampy)M(μ-CN)2(CN)2]n [ampy=4-aminomethylpyridine, M=Ni(II) (1), Pd(II) (2) and Pt(II) (3)]，已经通过振动光谱（FT-IR 和拉曼）、单晶 X 射线衍射、热分析和元素分析进行了表征。这些配合物在三斜晶系中结晶，空间群为 P-1。在所有配合物中，M(II) 离子由四个氰配体配位，铜原子周围的赤道平面的四个 N 原子形成略微扭曲的平面四方排列，而轴向位置的氰化物 N 原子完成略微扭曲的八面体配位。在所有配合物的一维结构中，[Cu(ampy)]2+阳离子和[M(CN)4]2-阴离子通过桥接氰基配体连接。相邻的一维结构通过μ-ampy 桥接配体形成二维网络进行连接。二维层通过金属⋯π 和氢键相互作用进一步连接，生成三维网络。
