Abstract

Tris-glycine zinc chloride, a complex of glycine with ZnCl2, crystallises in an orthorhombic unit cell of dimensions a = 11.230(2) Å b = 15.251(3) Å c = 15.564(4) Å in the space group Pbn21 with Z = 8. The structure has been determined using diffractometer data (2345 Mo reflections) to a final R value of 0.034.

All the six glycine molecules in an asymmetric unit exist as zwitterions, NH3+CH2COO and are held together by a network of N – H…O and N – H…Cl type of hydrogen bonds. Each of the two zinc atoms is coordinated to two oxygen atoms and two chlorine atoms, forming a distorted tetrahedron.
