A novel aroylbisthiourea, H3pyr(Et2tu)2 (V), has been prepared from 2,5-pyrroledicarboxylic chloride, NH4SCN and diethylamine. The compound reacts with (NBu4)[ReOCl4] in MeOH under formation of the dimeric oxidorhenium(V) complex [{ReO(OMe)}2{Hpyr(Et2tu)2}2] (VI), which undergoes a condensation in wet acetonitrile and forms the μ-oxido-bridged tetramer [(Re2O3)2{Hpyr(Et2tu)2}4] (VII). The pyrrole rings remain protonated and do not contribute to the coordination of the transition metal. The tetrameric complex is able to accommodate a molecule of water in its molecular cavity.
Graphical abstractA novel aroylbisthiourea reacts with (NBu4)[ReOCl4] under formation of a dimeric oxidorhenium(V) complex or the cage-like tetramer [(Re2O3)2{Hpyr(Et2tu)2}4] depending on the conditions applied. The tetrameric complex hosts a molecule of water in the central cavity.Figure optionsDownload full-size imageDownload as PowerPoint slide
