• X-ray crystal structure
• Zinc(II)-arginine complex
• Acetato ligand
• Salt bridged acetate

The synthesis and X-ray crystal structure of acetatobis(L-arginine) zinc(II) acetate trihydrate, [Zn(OAc)(L-Arg)(2)]OAc center dot 3H(2)O is reported. In this structure, the first of a zinc(II)-arginine complex to be reported, the geometry around zinc(II) is distorted square-pyramidal containing two trans-N,O chelated L-Arg ligands in the basal plane and the acetato ligand in an axial position. The structure contains a second acetate which is salt-bridged to the delta and omega NH groups of the guanidinium side chain of an arginine ligand and also contains three hydrogen bonded water molecules.
