In order to determine the structure of trans-bis(N-ethylidene-DL-threoninato)copper (II) dihydrate (α-form), X-ray crystal analysis was carried out on a single crystal, chiefly on (010) face, using Patterson and Fourier projection. This crystal has two molecules in unit lattice, is a monoclinic, and its space group is P21/c. The dimensions of the monoclinic cell are: a=11.41 Å, b=7.26 Å, c=10.63 Å, β=100°. From the electron density projection obtained from structural analysis, this chelate was found to have OH and COOH groups coordinating to the copper atom in a square planar and its ligand is a Schiff base with N-ethylidene group.
