Reaction of Co(ClO4)(2) center dot 6H(2)O with N,N-diisopropylisonicotinamide (L) has yielded a 1-D coordination polymer [{Co(L)(2)(H2O)(2)}(ClO4)(2)(CH3COCH3)(2)(H2O)(2)](n) (1). Complex 1 has been characterized by infrared (IR) and UV-Vis spectroscopies, thermal analysis, and single crystal X-ray diffraction techniques. The structure has alternate arrangement of parallel 1-D cationic metal-ligand chains and H-bonded anionic chains containing perchlorate, acetone and water in the lattice. Further hydrogen bonding among both chains leads to formation of 2-D networks along almost perpendicular planes. Interpenetrations of such perpendicular 2-D sheets create a 3-D supramolecular structure.
