Abstract

The crystal and molecular structure of bis(1-vinylimidazole)diacetatozinc (C14H18N4O4Zn), a highly effective antidote and antihypoxic drug, was determined [R 1 0.0335 for 8902 unique reflections with I > 2σ(I) and wR 2 0.0931 for all 10 752 unique reflections]. The triclinic unit cell contains two independent molecules of the complex, A and B. These molecules have short contacts O⋯H-C. The zinc atoms in molecules A and B have distorted tetrahedral coordination with the coordination sites occupied by the imidazole nitrogen atoms and acetate oxygen atoms. The lengths of the Zn-N bonds (2.019–2.050 Å) and Zn-O bonds with three acetate groups (1.956–1.958 Å) are typical for zinc complexes, whereas the Zn-O3 bond with one of the acetate groups in molecule A is somewhat longer, 2.009(1) Å; also, there is an additional contact of the zinc atom with the carbonyl oxygen atom of this group (Zn-O4 2.498 Å).
