<abstract xmlns="http://www.w3.org/1999/xhtml"> Two homodimetallic dipicolinate compounds of the formulae [Co(H2O)5Co(dipic)2]·2H2O (1) and [Ni(H2O)5Ni(dipic)2]·2H2O (2) have been synthesized and their crystal structures have been determined by single-crystal X-ray diffraction analysis. The prepared isostructural compounds consist of cationic {MO5O’}2+ and anionic {MN2O4}2- moieties, where CoII/CoII or NiII/NiII metal centers are connected together by bridging μ-carboxylate oxygen atoms from dipicolinate anions. H-bond interactions involving aqua ligands, dipicolinate oxygens and lattice solvent molecules stabilize the dimeric units by linking them into 3-D polymeric networks. </abstract>
