Crystal structure of ether solvate of octanuclear lutetium aluminohydride complex [(Bu{sub 2}{sup t}C{sub 5}H{sub 3})LuH]{sub 4}[Et{sub 2}O{center_dot}AlH{sub 4}]{sub 2}[AlH{sub 4}]{sub 2}{center_dot}Et{sub 2}O
Overall X-ray structural analysis (XSA) of ether solvate crystals of the unusual octanuclear lutetium aluminohydride complex [(Cp{double_prime}LuH){sub 4}(Et{sub 2}O{center_dot}AlH{sub 4}){sub 2}(AlH{sub 4}){sub 2}]{center_dot}Et{sub 2}O (I) (Cp{double_prime} = 1.3-Bu{sub 2}{sup t}C{sub 5}H{sub 3}) is reported. In complex I, four Lu atoms are located in vertices of an elongated tetrahedron; over each face of the tetrahedron there is one Al atom. The octanuclear metal core of I is a very distorted cube with an approximate point symmetry D{sub 2d} formed by the bridging hydrogen bonds (covalent metal-metal bonds are absent in I). Each Lu atom in I (neglecting individual H and C atoms) has the same distorted square-pyramidal coordination with the {eta}{sup 5}-Cp{double_prime} ring in the apical position and three Al atoms and the nearest Lu atom in the base of the pyramid.
