[Nb6Cl12(CH3OH)4(OCH3)2] ⋅ DABCO ⋅ 1.66 CH2Cl2: Cluster Units Wrapped in a Network of Hydrogen Bonds.

An easy‐to‐do synthesis for the hexanuclear niobium cluster compound [Nb6Cl12(CH3OH)4(OCH3)2] ⋅ DABCO ⋅ 1.66 CH2Cl2 has been developed. An one‐pot reaction between the cluster precursor [Nb6Cl14(H2O)4] ⋅ 4H2O 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 FROM AUTHOR]
