Abstract

The nucleophilic addition of methanol and water to the dicyanonitrosomethanide anion, resulting in the formation of cyano(imino(methoxy)methyl)nitrosomethanide (cmnm) and carbamoylcyanonitrosomethanide (ccnm), respectively, is used as a means of in situ ligand synthesis during the formation of [Dy8(OH)6(OMe)6(cmnm)10(ccnm)2(H2O)2(MeOH)2] (1). This is the first time these reactions have been observed to be promoted by the presence of a lanthanoid ion. The core of the octanuclear cluster consists of two cubane moieties ([Dy4(OH)3(OMe)]), bridged by four methoxide ligands to form a central [Dy8(OH)6(OMe)6] moiety. The complex displays magnetic properties that are indicative of probable single molecule magnet features.
