title: Poly[4,4'-imino-dipyridinium [di-μ(4)-isophthalato-κO:O':O'':O''-di-μ(3)-iso-phthal-ato-κO:O':O'';κO:O':O'',O'''-trizinc(II)] dihydrate].
abstract: In the title compound, {(C(10)H(11)N(3))[Zn(3)(C(8)H(4)O(4))(4)]·2H(2)O}(n), divalent Zn atoms are linked into trinuclear units featuring tetra-hedral, octa-hedral and distorted tetrahedral, octahedral and square-pyramidal coordination geometries. These trinuclear units are connected by isopthalate dianions into [Zn(3)(isophthalate)(4)](n) (2n-) anionic layers, which aggregate into the three-dimensional structure via hydrogen-bonding pathways mediated by doubly protonated 4,4'-imino-dipyridinium cations and water mol-ecules of crystallization. One solvent water mol-ecule was found to be disordered over two positions, each with a 50% site-occupancy factor.
