Abstract

Abstract: An easy‐to‐do synthesis for the hexanuclear niobium cluster compound [Nb6 Cl12 (CH3 OH)4 (OCH3 )2 ] ⋅ DABCO ⋅ 1.66 CH2 Cl2 has been developed. An one‐pot reaction between the cluster precursor [Nb6 Cl14 (H2 O)4 ] ⋅ 4H2 O and methanol with the addition of DABCO leads to the crystallization of the title compound in high yield within a few minutes. The single‐crystal X‐ray structure of this cluster compound has been determined. Very strong, nearly symmetric intercluster hydrogen bonds Nb6 −MeO⋅⋅⋅H⋅⋅⋅OMe−Nb6 are present between the cluster units. A bridging co‐crystalline DABCO molecule is also involved in a three‐dimensional hydrogen‐bonding network. Abstract : An easy‐to‐do preparative procedure yields the hexanuclear niobium cluster compound [Nb6 Cl12 (CH3 OH)4 (OCH3 )2 ] ⋅ DABCO ⋅ 1.66 CH2 Cl2, which comprises hydrogen‐bonded sheets of neutral cluster molecules and H‐bonded chains of cluster‐DABCO units.
