Summary
Two novel copper(II) complexes, Cu 2 L 2 (bipy) and Cu 2 L 2 (H 2 O) 4 ·3H 2 O of Schiff base ligands derived from the condensation of L- tert -leucine and L-isoleucine with 2,4-dihydroxybenzaldehyde, are synthesized and characterized by single crystal X-ray diffraction. Compounds crystallize in the orthorhombic crystal system. The Cu 2 L 2 (bipy) complex has a distorted square planar geometry with an N 2 O 2 coordination environment. Water is contained in supramolecular network pores. On the other hand, in the Cu 2 L 2 (H 2 O) 4 ·3H 2 O complex, both copper atoms adopt a five-coordinated distorted square-pyramidal geometry with an NO 4 coordination environment and guest water molecules form a 1D water chain. Both complexes build a 2D supramolecular network.
