Two polymorphic forms of a mixed zinc/copper biquinoline dihydrogenphosphate

Abstract: Two polymorphic forms of a mixed zinc/copper biquinoline dihydrogenphosphate are presented, showing almost identical monomeric units, viz. (2,2'-biquinoline-²N,N')bis(dihydrogenphosphato-O)copper(II)/zinc(II), formulated as [Zn_xCu_1-x(H₂PO₄)₂(C₁₈H₁₂N₂)], with x = 0.88 (1) and 0.90 (2). The cation is tetrahedrally coordinated to a chelating biquinoline system and two diprotonated phosphate anions. The structures differ mainly in their intermolecular hydrogen-bonding interactions, leading to different packing schemes. No significant evidence of stress due to the Zn/Cu solid solution formation was detected.

Formula: [Zn_0.88Cu_0.12(H₂PO₄)₂(C₁₈H₁₂N₂)] and [Zn_0.90Cu_0.10(H₂PO₄)₂(C₁₈H₁₂N₂)]
