Four 3d–4d heterometallic coordination polymers, were synthesized under hydrothermal conditions. The single-crystal X-ray diffraction analysis reveals that complexes 1–3 are isostructural; the complex 4 exhibits a three-dimensional architecture constructed by planar {AgCu4N12} units. •Four novel 3d–4d coordination polymers have been synthesized.•Compounds 1, 2 and 4 show a strong antiferromagnetic coupling.•The H3TzDC ligand exhibits diverse coordination modes.•The complex 4 shows a 3D architecture constructed by planar {AgCu4N12} units. Four 3d–4d heterometallic coordination polymers, [Ag2M(HTzDC)2·3H2O]n(M=Co(1), Ni(2), Zn(3) and {[(CH3)2NH2][AgCu5(TzDC)4·6H2O]·6H2O]}n(4) (H3TzDC=1,2,3-triazole-4,5-dicarboxylic acid) were synthesized under hydrothermal conditions using one-step approach and structurally characterized by elemental analysis, FT-IR, power X-ray diffraction and single-crystal X-ray diffraction. The single-crystal X-ray diffraction analysis reveals that complexes 1–3 are isostructural, the three dimensional frameworks is composed of Ag ions and transition metals which linked by TzDC ligands; the complex 4 exhibits a three-dimensional architecture constructed by planar {AgCu4N12} units. The magnetic properties of compounds 1–2 and 4 were investigated.
