Synthesis and quantum chemistry of two novel copper(II) complexes

The reaction of Cu(NO3)(2) with N'[(2-hydroxyphenyl) methylidene]-2-(4-methyl)acetohydrazide (sal-mphah) led to the formation of a one-dimensional coordination polymer with the empirical formula of [Cu(sal-mphah)-H2O](n) (1(.)H(2)O)While, the reaction of Cu(NO3)(2) with salicylidene-[1-(t-buty)5-methyl-1H-pyrazole]-formhydrazine (sal-pfh) gave a dinuclear Cu(II) compound [Cu(sal-pfh)(2)(.)(mu-NO3)(2)] (2). The electronic studies of the ligands and their copper(I) complexes have been calculated with density functional theory (DFT/B3LYP) and the coordination character was further discussed.
