Crystal structure of the aziridinylgallane trimer

Abstract

Crystals of the title compound are orthorhombic, a= 18·364(5), b= 10·823(3), c= 7·114(2)Å, Z= 4 (trimeric units), space group Pnma. The structure was determined from diffractometer data by Patterson and Fourier syntheses, and refined by full-matrix least-squares methods to R 0·077 for 252 observed reflexions. The six-membered (Ga–N)₃ ring is in the chair conformation, torsion angles 59—61°, and lies on a crystallographic mirror plane. The mean dimensions are Ga–N 1·97, N–C 1·55, C–C 1·55 Å; N–Ga–N 100, Ga–N–Ga 121, Ga–N–C 116°, angles in three-membered rings ca. 60°.
