Source of material
All commercially available starting materials were used without further purification. The titled compound was obtained from slow evaporation reaction of H4B4C (benzene-1,2,4,5-tetracarboxylic acid) (1 mmol), Cu(NO3)2·3H2O (1 mmol), Zn(CH3COO)2·2H2O (1 mmol) in 20 ml of MeOH–H2O (1:1, v/v) mixture. The reaction mixture was heated for 15 min while stirring. Then it was allowed to cool down. The resulting solution was filtered, covered with parafilm and kept aside in a secluded area for nine days to allow for the growth of blue crystal of the titled compound. Elemental analysis (calcd.)(%) C, 27.95 (28.34), H, 3.25 (3.81), Cu, 14.99 (14.72).
Experimental details
Carbon-bound H atoms were placed in calculated positions and were included in the refinement in the riding model approximation, with U(H) set to 1.2 Ueq(C).
The H atom of the hydroxyl group was allowed to rotate with a fixed angle around the C–O bond to best fit the experimental electron density (HFIX 147 in the SHELX program suite (Sheldrick, 2015)), with Uiso(H) set to 1.5Ueq(O).
Comment
Pyromellitic acid (H4B4C), the most symmetrical of the three benzenetetracarboxylic acids [8] is a member of benzenepolycarboxylic acid family and has found applications in the hydrogen-bond formation. The salts of this acid [9] are also of interest in gravimetric analysis, heat stabilizers, detergent builders, catalysts and applied dyes [10]. The crystal structure of title compound is built from [Cu(H2O)6]2+ dications and doubly deprotonated pyromellitic dianions, (H2B4C)2− which are linked to each other through hydrogen bonds and ionic interactions. Similar structures such as {Co(H2O)6}{C10H4O8} [10], {M(H2O)6}{C6H2(COO)2(COOH)2} with M=Mn, Co, and Ni [11] and [Mg(H2O)6](
