Two new heteronuclear (Ni/Cd and Pd/Cd) 2D coordination polymers formulated as namely {[Cd(μ-3aepy)₂Ni(μ-CN)₂(CN)₂]⋅2H₂O}_n (1) and [Cd(3aepy)Pd(μ₄-CN)₄]_n (2) (3aepy = 3-(2-aminoethyl)pyridine) were obtained and determined using different techniques (FT-IR and Raman spectroscopies, single crystal X-ray diffraction, elemental, SEM–EDX and thermal analyses). Single crystal X-ray study of the complexes revealed that the Ni(II) and Pd(II) ions are coordinated with four cyanide-carbon atoms in square planar geometries. The Cd(II) ions are bridged by 3aepy ligands to generate [Cd₂(3aepy)₂]²⁺ cation and adjacent cations are further linked to cyanide ligands from [Ni(μ-CN)₄]²⁻ anion, generating corrugated rectangular grid-like 2D sheets in 1. Whereas, the Cd(II) and Pd(II) ions are bridged by cyanide ligands, generating corrugated rectangular grid-like 2D sheets in 2. The Cd1 is possessed the distorted octahedral coordination geometry with six nitrogen atoms from two 3aepy and four cyanide ligands. The Cd2 is coordinated by four nitrogen atoms from cyanide ligands to form a square-planar geometry. Furthermore, the most remarkable properties of the complexes are the existence of the intermolecular C–H⋯M interactions between M(II) and hydrogen atoms of the 3aepy ligands (M(II) = Ni and Pd).

两个新的异核（镍/镉和Pd / Cd）的2D配制为即{[CD（μ-3aepy）配位聚合物₂的Ni（μ-CN）₂（CN）₂ ]⋅2H ₂ ö} _Ñ（1）和[镉（3aepy）的Pd（μ ₄ -CN）₄ ] _ñ（2）（3aepy = 3-（2-氨基乙基）吡啶）获得并使用不同的技术（FT-IR和拉曼光谱测定，单晶X射线衍射，元素，SEM-EDX和热分析）。对配合物的单晶X射线研究表明，Ni（II）和Pd（II）离子与正方形平面几何形状中的四个氰化物-碳原子配位。Cd（II）离子被3aepy配体桥接以生成[Cd₂（3aepy）₂ ] ²⁺阳离子和相邻的阳离子进一步与[Ni（μ-CN）₄ ] ^2-阴离子的氰化物配体连接，在1中生成波纹状矩形网格状2D片。而Cd（II）和Pd（II）离子被氰化物配体桥接，从而在2中生成波纹状矩形网格状2D板。Cd1具有扭曲的八面体配位几何结构，具有来自两个3aepy和四个氰化物配体的六个氮原子。Cd2由来自氰化物配体的四个氮原子配位，以形成正方形平面的几何形状。此外，配合物最显着的性质是M（II）与3aepy配体的氢原子之间的分子间C–H⋯M相互作用（M（II）= Ni和Pd）。
