✦ Synopsis

In the solid state, the title compound, [Zn(C 8 H 4 O 4 )-(C 5 H 8 N 2 ) 2 ] n , exhibits polymeric zigzag chains extended along th c axis. Each Zn II ion is coordinated by two N and two O atoms in a distorted tetrahedral geometry. Weak C-HÁ Á ÁO interactions contribute to the crystal packing stability.
