Abstract
As part of our synthetic efforts for new triplesalen derivatives, we reacted 2,4,6-triacetyl- 1,3,5-trihydroxybenzene (1) with excess Cu(ClO4)2 · 6H2O, imidazole, and ethylenediamine. However, not the triple ketimine derivative was formed but the mononuclear CuII complex [LCuII(ImH)]ClO4 · 0.5EtOH · 0.5H2O (HL = 6-(1-(2-aminoethylimino)ethyl)-2,4-diacetyl-1,3,5-trihydroxybenzene) with only one ketimine function. This complex forms a one-dimensional coordination polymer in the solid state through the apical binding of a keto-oxygen atom of one cation to the CuII ion of a neighboring cation. Magnetic measurements reveal the presence of weak antiferromagnetic intra-chain interactions
