Abstract / Description of output
The structures of dimethylgallium tetrahydroborate and its 1 : 1 adducts with diethyl ether and tetrahydrofuran have been investigated by single crystal X-ray diffraction at low temperatures. The structure of dimethylgallium tetrahydroborate has been shown to consist of discrete GaMe2(BH4) units in which each BH4 group exhibits bidentate ligation to a single Me2Ga unit, but in which there are long-range interactions between the Ga and the terminal hydrogen atom of a BH4 group in each of two neighbouring molecules. The structures of the adducts show that they are composed of molecules in which the Ga is 5-coordinate and asymmetrically bound to a bidentate BH4 unit. The adducts display enhanced thermal stability compared to that of uncoordinated GaMe2(BH4), but reversibly dissociate in the gas phase at ambient temperature. The infrared spectra of the compounds are discussed on the basis of their structures.
