Abstract

The crystal structure of the title compound, [Cd(C29H29N5)2](C6H2N3O7)2, consists of CdII complex cations and picrate anions. In the complex cation, the CdII ion is chelated by two bis­(1-allyl­benzimidazol-2-ylmeth­yl)benzyl­amine (babb) ligands in a distorted octa­hedral geometry. Extensive C—H⋯O hydrogen bonding occurs between cations and anions in the crystal structure.
