dc.description.abstractTemperature dependent synthesis and crystal structure of the dicopper(II) complex [Cu2(L-jONO0 )2(l- 4,40 -bipy)(DMF)2] (1) and the dicopper(II) based coordination polymer [Cu2(l-L-1jONO0 :2jO)2(l-4, 40 -bipy)]nnH2OnDMF (2) derived from the acyclic Schiff base 2-[(2-hydroxy-3-methoxyphenyl)methylideneamino]benzenesulfonic acid (H2L) are described. Compounds 1 and 2 crystallize in monoclinic P21/n and P21/c systems, respectively. Crystal structure analysis reveals that the coordination polymer 2 consists of a dimeric building block which is comparable to the basic structure of 1. The compounds are isolated from the same reaction mixture but at different reaction temperatures and 1 can be converted into the coordination polymer 2. They were tested as catalysts for (both primary and secondary) alcohols oxidation. They show good catalytic activity for the solvent- and additive-free microwave (MW) assisted peroxidative (with tert-butylhydroperoxide) oxidation of cyclohexanol (up to 85% yield of cyclohexanone) after 30 min of low power MW irradiation. 2pt_PT
