Abstract

The complex (η6-catechol)Mn(CO)3+ is readily deprotonated to (η4-o-benzoquinone)Mn(CO)3- (o-QMTC), which functions as an organometalloligand toward divalent metal ions by σ-bonding through the quinone oxygen atoms. The ligand o-QMTC, together with 2,2′-bipyridine or 1,10-phenanthroline (L-L), was found to produce the stable complexes M(o-QMTC)2(L-L) (M = Mn, Co, Cd). Crystal structures of Mn(o-QMTC)2(bipy), Co(o-QMTC)2-(bipy), and Cd(o-QMTC)2(phen) revealed in each case a two-dimensional supramolecular architecture consisting of π - π stacking and interdigitation of the bipy or phen ligands, as well as a pairwise π - π stacking of one of the two benzoquinone rings in each monomeric unit to generate dimeric units.
