Unusual constructions of two Salamo-based copper(II) complexes

Through the self-assembly of an asymmetric salamo-type bioxime ligand H2L1 with Cu(OAc)2·2H2O, two unusual Cu(II) complexes, [{Cu(L1)}2] (1) and [Cu2(L2)] (2) were obtained and characterized structurally. Meanwhile, the photophysical spectra and Hirshfeld surface analyses of the complexes 1 and 2 were also discussed.131
