TLDR
The reaction of Zn(NO3)2 with pyridine-2,6-dicarboxylic acid and acridine in aqueous solution leads to the formation of the title compound, (C13H10N), where the ZnII atom is coordinated by four O atoms and two N atoms from the tridentate chelating rings of ( pydc)2− and (pydcH)− anions.Abstract:
The reaction of Zn(NO3)2 with pyridine-2,6-dicarboxylic acid (pydcH2) and acridine (acr) in aqueous solution leads to the formation of the title compound, (C13H10N)[Zn(C7H3NO4)(C7H4NO4)]·5H2O or (acrH)[Zn(pydcH)(pydc)]·5H2O. In the title compound, the ZnII atom is coordinated by four O atoms and two N atoms from the tridentate chelating rings of (pydc)2− and (pydcH)− anions. The geometry of the resulting ZnN2O4 coordination can be described as distorted octahedral. To balance the charges, one protonated acridine (acrH)+ cation is present. In the crystal structure, extensive O—H⋯O and N—H⋯O hydrogen bonds involving acrH+, the complex anion and uncoordinated water molecules form a three-dimensional network.read more
