Abstract
The crystal structure of the title compound, {(C13H10N)2- [Zn(C6H2N2O4)2]}n, consists of polymeric Zn complex anions and discrete acridinium cations. The Zn cation, located on an inversion center, is N,O-chelated by two pyrazine-2,3- dicarboxylate (pyzdc) anions in the basal plane, and is further coordinated by two carboxylate O atoms from adjacent pyzdc anions in the axial directions with a longer Zn—O bond distance, forming a distorted ZnN2O4 coordination geometry. The pyzdc anions bridge the Zn cations, forming polymeric chains running along the crystallographic b axis. The acridinium cations are linked to the complex chains via N— H O and C—H O hydrogen bonding. Significant – stacking between parallel acridinium ring systems is observed in the crystal structure, face-to-face distances being 3.311 (3) and 3.267 (4) A ° .
