In the title three-dimensional heterometallic complex, {[AgDy(C(6)H(4)NO(2))(2)(C(2)H(3)O(2))(H(2)O)]ClO(4)}(n), the Dy(III) ion is eight-coordinated by four O atoms from four different isonicotinate ligands, three O atoms from two different acetate ligands and one O atom of water mol-ecule. The two-coordinate Ag(I) ion is bonded to two N atoms from two different isonicotinate anions. These metal coordination units are connected by bridging isonicotinate and acetate ligands, generating a three-dimensional network. The coordinated water mol-ecules link the carboxyl-ate group and the acetate ligand by O-H⋯O hydrogen bonding. The perchlorate anion is disordered over two sites with site occupancy factors 0.508 (12) and 0.492 (12) and the methyl group of the acetate ligand is disordered over two positions of equal occupancy.
在标题化合物三维异金属配合物{[AgDy(C₆H₄NO₂)₂(C₂H₃O₂)(H₂O)]ClO₄}ₙ中，Dy(III)离子由来自四个不同异烟酸酯配体的四个O原子、来自两个不同乙酸酯配体的三个O原子和一个水分子的O原子八配位。两配位的Ag(I)离子与来自两个不同异烟酸根阴离子的两个N原子键合。这些金属配位单元通过桥连的异烟酸酯和乙酸酯配体相连，形成三维网络。配位水分子通过O—H⋯O氢键连接羧酸根基团和乙酸酯配体。高氯酸根阴离子在两个位置无序，占位因子分别为0.508 (12)和0.492 (12)，乙酸酯配体的甲基在两个占有率相等的位置无序。
