چکیده
The title benzyl Grignard reagent, [Mg(2)Br(2)(C(7)H(7))(2)(C(4)H(10)O)(2)], was obtained by reaction of benzyl bromide with magnesium in diethyl ether, followed by crystallization from toluene. The asymmetric unit comprises one half-mol-ecule, the structural dimeric unit being generated by inversion symmetry with an Mg⋯Mg distance of 3.469 (2) Å. The Mg(II) atom exhibits a distorted tetrahedral coordination geometry. The crystal packing is defined by van der Waals inter-actions only.

The crystal structure of the title compound, [Mg2Br2(C9H11)2(C4H10O)2], features a centrosymmetric two-centre magnesium complex with half a mol-ecule in the asymmetric unit. The Mg atom is in a considerably distorted Br2CO coordination. Bond lengths and angles are comparable with already published values. The crystal packing is stabilized by C-H⋯π inter-actions linking the complexes into sheets...

The half-sandwich title compound, [Yb(2)(C(13)H(21))(2)I(2)(C(4)H(10)O)(2)], crystallizes as a centrosymmetric dimer. The Yb atom is coordinated in a three-legged piano-stool geometry by a cyclo-penta-dienyl ring, two I anions and the O atom of a diethyl ether mol-ecule. The central Yb(2)I(2) core is an approximate square.
