摘要：
The title compound was prepared by reacting gallane etherate H3Ga.OEt2 at -40-degrees-C in Et2O with diethylamine upon warming to room temperature for several hours. It forms white crystals from ether solution which were identified by X-ray structure determination. Space group C2/c, Z = 4; 930 observed unique reflections, R/wR = 0.0482/0.0450. Lattice dimensions at 193 K: a = 1292.9(3), b = 721.1(2), c = 1443.1(2) pm; beta = 92.81(2)degrees. The structure reveals a centrosymmetric dimeric molecule with a planar square (GaN)2 fourmembered ring: average distance Ga-N 201.7 pm, Ga...Ga 284.5(2) pm.
