摘要
Mixed copper(H) chelates, [Cu(trop/hino)(tmen)]B(C6H5)(4), were prepared with a tropolonato or hinokitiolato ligands (trop/hino) and N,N,N',N'-tetramethylethylenediamine (tmen). These chelates were, as expected, quite similar to the corresponding acetylacetonato analog [Cu(acac)(tmen)]B(C6H5)(4), being fairly soluble in a large number of solvents and remarkably solvatochromic in them. They were also useful as excellent Lewis basicity indicators in solution because their d-d bands continuously shift to red in wider ranges with increasing DN (donor number) of solvent. The examination on addition of various anions to these solvatochromic systems led to a quantitative view of the competition between solvent molecule and anion for coordination to metal center.
