Abstract
Abstract The structure of an unsolvated adduct of dineopentylmagnesium and neopentylmagnesium bromide has been determined by a single crystal X-ray diffraction study. It consists of a polymeric chain of composition [(Np 2 -Mg) 2 · (NpMgBr) 2 ] n , involving an alternating pattern of two Np 2 Mg and two NpMgBr fragments connected by bridging neopentyl and bromide groups, in which all Mg atoms are tetracoordinate. Crystals of C 15 H 33 Mg 2 Br are triclinic, space group P 1, with unit cell dimensions a 9.654(1) A, b 9.876(1) A, c 11.334(2) A, α 85.35(1)°, β 67.93(1)°, γ 74.59(1)°, Z = 2, V 965.3 (2) A 3 , R = 0.0819 for 2447 reflections with I > 3.0σ( I ).
