摘要

The synthesis and the crystal structure of the ligand N,N,N"',Al"'-tetraisobutyl-N',AP'-isophthaloylbis(thiourea) and its C-II-complex are reported. The ligand co-ordinates quadridentately forming a di-bischelate. The donor atoms 0 and S are arranged in cis-position around the central Co-II ions. In addition the coordination geometry is determined by methanol molecules resulting in the co-ordination number five. The complex crystallizes in the space group P! (Z = 1) with two additional methanol molecules
