Aiming to create coordinative polymers of different dimensions there have been assembled two new coordinative polymers of the cobalt(II) with dicarboxylic acids and 4-pyridylamidoxime with the following fo1mulas: [Co(adi)(4-pyamo)2]n (1) and {[Co(tph)(4-pyamo)2]-2dmf.2H20}n (2) (H2adi - adipic acid, H2tph - terephthalic acid; 4-pyamo - 4-pyridylamidoxime). The X-ray study has established that both compounds c1ystallize in the triclinic P-1 space group. Each metal atom in both compounds have the octahedral coordination polyhedron, consisting of 04N2 donor atoms set going from two bideprotonated adipato anions and two neutral 4-pyamo ligands in 1, and two bideprotonated terephthalate and two neutral 4-pyamo ligands and two coordinated water molecules in 2. The 4-pyamo molecule coordinates to the Co(II) center in monodentate mode via the pyridine N-binding site, while the adipato anion coordinates in bis-chelating bridging mode and terephthalate anion in bridging bis-monodentate mode. Such coordinating mode of adipic acid dete1minated in 1, was established in some of the compounds with dicarboxylic acids and 4-pyridilaldoxime [1]. The bridging adi anions are responsible for ID z
