The methylzinc hydroborate derivative [(MeZn)2B3H7]2: synthesis, crystal structure and vibrational spectra of an unprecedented cluster compound
Abstract
The bis(methylzinc) derivative of triborane(9), prepared by the gas-phase reaction of B4H10 with Me2Zn at ambient temperature, is a dimer [(MeZn)2B3H7]2 with an unprecedented structure featuring two distinct zinc environments; two B3H7ZnMe ligands, formally derived from B3H8 by replacement of a µ2-H by a µ2-ZnMe unit, each function in a bis(bidentate) manner linking together two other MeZn centres through pairs of Zn–H–B bridges.
