Abstract: In the title compound, [Zn(C₂H₃O₂)₂(C₂H₈N₂)], the Zn^II atom is coordinated by two N atoms of one bidentate ethylenediamine ligand and two O atoms of two acetate anions in a distorted tetrahedral geometry. The compound displays [4+2] coordination, the `4' representing the distorted tetrahedral coordination, while the `2' refers to the two much longer ZnO(uncoordinated) distances of 2.594 (2) Å. The asymmetry of the acetate coordination is reflected in the different C-O distances of 1.229 (2) and 1.280 (2) Å. The Zn atom lies on a crystallographic twofold rotation axis. The dihedral angles between the N/Zn/N' plane and the two O/Zn/O' planes are 85.54 (7) and 29.96 (7)°, where the prime denotes the atom related by operation of the twofold axis. N-HO hydrogen bonding links the molecules into a three-dimensional network.
