The respective reactions of the Mn II ion with the homologous ligands 2-aminoterephthalic acid and terephthalic acid afforded two novel manganese-organic compounds, [Mn(2-atp)(bipy-eta) 0.5 ] n (1) and {[Mn(tp)(bipy-eta) 1.5 ]·2H 2 O} n (2). These two compounds were characterized by IR spectroscopy, elemental analysis, and single-crystal X-ray diffrac-

Key indicators: single-crystal X-ray study; T = 173 K; mean (C-C) = 0.004 Å; R factor = 0.033; wR factor = 0.074; data-to-parameter ratio = 17.0.In the crystal structure of the title compound, (C 6 H 8 N)-[ZnCl 4 ]ÁH 2 O, the Zn atom has a tetrahedral geometry and is coordinated by four Cl atoms. The water molecule and phenylammonium cations interact with two [ZnCl 4 ] 2À anions, forming discrete structural motifs via O-HÁ Á ÁCl and N-HÁ Á ÁCl/O interactions. Intermolecularstacking is present between adjacent phenylammonium cations (centroidcentroid distance = 3.672 Å ).
