Title: Cobalt-5-aminoisophthalate: [Co(AIPA)(OH2)(2)](n)center dot nH(2)O: a new one-dimensional rail-road polymer with occluded water molecules

Abstract: A new structural form of cobalt-5-aminoisophthalate, [Co(AIPA)(OH2)(2)h center dot nH(2)O (1) has been synthesized from the reaction Of CoCl2 center dot 6H(2)O with 5-aminoisophthalic acid (AIPA-H-2) in a 1:1 molar ratio at room temperature by layering aqueous solutions of the starting materials over a period of 2-3 weeks. [Co(AIPA)(OH2)(2)h-nH(2)O (1) has been characterized by elemental analysis, IR spectroscopy, and single crystal X-ray diffraction studies. [Co(AIPA)(OH2)(2)]n center dot nH(2)O (1) crystallizes in triclinic space group P (1) over bar (a = 7.549(2) angstrom, b = 8.833(2) angstrom, c = 9.080(2) angstrom, alpha = 62.23(3)degrees, beta = 75.09(3)degrees, gamma = 81.52(3)degrees). Compound 1 forms a rail-road like 1-D polymeric structure which is held together in the lattice by a variety hydrogen bonds aided by the presence of lattice water molecule. The CO2+ ion is in a severely distorted octahedral geometry with a CoO5N coordination environment.
