title: Tetraaqua(2,2'-bipyridine)nickel(II) terephthalate.
abstract: The reaction of nickel(II) nitrate with terephthalic acid and 2,2'-bipyridine in dimethylformamide solution gives the title complex, [Ni(C(10)H(8)N(2))(H(2)O)(4)](C(8)H(4)O(4)). The Ni(II) ion is octahedrally coordinated to one 2,2'-bipyridine and four water molecules and does not coordinate to the terephthalate anion. Hydrogen bonds between the terephthalate anions and the [Ni(2,2'-bipy)(H(2)O)(4)](2+) cations produce a two-dimensional hydrogen-bonding architecture with double sheets.
