Poly[4,4'-iminodipyridinium [di-₄-isophthalato-⁴O:O':O'':O''-di-₃-isophthalato-³O:O':O'';⁴O:O':O'',O'''-trizinc(II)] dihydrate]

Abstract: In the title compound, {(C₁₀H₁₁N₃)[Zn₃(C₈H₄O₄)₄]·2H₂O}_n, divalent Zn atoms are linked into trinuclear units featuring tetrahedral, octahedral and distorted tetrahedral, octahedral and square-pyramidal coordination geometries. These trinuclear units are connected by isopthalate dianions into [Zn₃(isophthalate)₄]_n^2n- anionic layers, which aggregate into the three-dimensional structure via hydrogen-bonding pathways mediated by doubly protonated 4,4'-iminodipyridinium cations and water molecules of crystallization. One solvent water molecule was found to be disordered over two positions, each with a 50% site-occupancy factor.
