The 4d-4f heteronuclear title complex, AgCe(C(14)H(8)N(2)O(5))(2)(H(2)O), has a three-dimensional framework structure, generated by the carboxyl-ate and pyridyl groups of the 5-(isonicotinamido)-isophthalate (INAIP) ligands bridging the metal ions. The Ce(III) atom is coordinated by eight O atoms from six INAIP ligands and a water mol-ecule in a distorted tricapped trigonal-prismatic geometry, while the Ag(I) atom has a distorted trigonal-planar AgN(2)O geometry. O-H⋯O and N-H⋯O hydrogen bonds and π-π inter-actions between the pyridine and benzene rings [centroid-centroid distances = 3.642 (4) and 3.624 (3) Å] stabilize the crystal structure.
4d - 4f异核标题配合物[AgCe(C₁₄H₈N₂O₅)₂(H₂O)]ₙ具有三维骨架结构,由5 -(异烟酰胺基)间苯二甲酸酯(INAIP)配体的羧酸根和吡啶基桥连金属离子形成。Ce(III)原子由来自六个INAIP配体的八个O原子和一个水分子配位,呈扭曲的三帽三角棱柱几何构型,而Ag(I)原子具有扭曲的三角平面AgN₂O几何构型。O - H⋯O和N - H⋯O氢键以及吡啶环和苯环之间的π - π相互作用[质心 - 质心距离 = 3.642 (4) 和3.624 (3) Å]稳定了晶体结构。
