Dedicated to Professor Hansgeorg Schnöckel on the occasion of his 65th birthdayThe term "metalloid cluster" was coined by Schnöckel and coworkers in the context of Al chemistry to designate those metal clusters in which "the number of metal-metal contacts exceeds the number of metal-ligand contacts and by the presence of metal atoms which participate exclusively in metal-metal interactions".
The reactions of the digermanium and ditin alkyne analogues Ar'MMAr' (M = Ge or Sn) with R2NO, (R2NO = Me2C(CH2)3CMe2NO or N2O), result in complete MM bond cleavage to afford the germylene :Ge(Ar')ONR2 or the germanium(II) or tin(II) hydroxides {M(Ar')(micro-OH)}2.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
