Abstract	New coordination polymers of general form, [CoL2X2]n (L = 3,3’-oxybis(pyridine) (obp), 1,4-bis(3-pyri-doxy) benzene (bpob); X = Cl, NCS), have beenprepared via a slow diffusion method. The reaction of the present linkers with cobalt(II) ion affords infinite 2-dimensional sheet products. For [Co(obp)2Cl2]n, the local geometry of the cobalt center is an octahedral arrangement withfour nitrogen donors and two chlorine ions in trans positions. [Co(bpob)2(NCS)2]n has provided a similar structure: the local geometry of the cobalt atom is an octahedral arrangement with four pyridine units and two NCS groups in transpositions. The obp and bpob linkers connect two cobalt(II) ions defining the edges of 40- and 60-membered [Co(II)]4 ring, respectively. Thermal analyses of the coordination polymers show significant thermal behavior associated with the charac-teristic structures.
