Three novel heterometallic microporous coordination polymers {M(Hnico)3M0}n (1, M = Co, M0 = K; 2, M = Ni, M0 = K; 3, M = Co, M0 = Na, Hnico is the anion of 2-hydroxy-nicotinic acid, where the proton is transferred from the phenolate hydroxy group to the nitrogen atom of imine pyridine ring) were synthesized by hydrothermal reaction between M(Ac)24H2O, M0OH and a multifunctional organic aromatic H2nico ligand and characterized by IR spectrum, elemental analysis, raman spectrum and the single crystal X-ray diffractions. In complexes 1–3, the M2? ions linked three different Hnico ligand formed [M(Hnico)3]- subunit which further interlinked the six-coordination M0? cation constructed 3D network. The network topology of 1–3 can be simplified a rare 3D (4,4)-connected (41263) net.
