Özet

Two novel copper(II) complexes, Cu2L2(bipy) and Cu2L2(H2O)(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 Cu2L2(bipy) complex has a distorted square planar geometry with an N2O2 coordination environment. Water is contained in supramolecular network pores. On the other hand, in the Cu2L2(H2O)(4)3H(2)O complex, both copper atoms adopt a five-coordinated distorted square-pyramidal geometry with an NO4 coordination environment and guest water molecules form a 1D water chain. Both complexes build a 2D supramolecular network.
