摘要：
The addition of the N-H bond of the formamidine, ArN(H)C=NAr (Ar = C6H3Pr21-2,6), to the gallium(I) center of [K(tmeda)] [ Ga(Ar-DAB)] (Ar-DAB={(Ar)NC(H)}(2)) yields K[(Ar-DAB)Ga-III(H){N(Ar)C=NAr}] 1 The crystal structure of this and two other related anionic compounds, [K(18-crown-6)][(Ar-DAB)Ga-III{N(H)N=Fl}{(H)Fl}] (Fl = fluorendiyl) 2 and [K(OEt2)(3)][(Ar-DAB)Ga-II(CH2Ph)Ga-II(Ar-DAB)] 3, have been determined The cell parameters of the compounds are 1 P2(1)/c, a = 20 2350(9), b = 14 1760(7), c = 19 6441(10), beta = 111 307(1), 2 P2(1)/c, a = 13 115(3) b = 21 799(4), c = 22 646(5), beta = 90 20(3), 3 P2(1)/n, a = 16 783(3), b = 21 635(4), c = 19 814(4), beta = 92 34(3) The crystal structures of all complexes exhibit distorted tetrahedral gallium centers, and interactions between anion aryl substituents and the potassium cations
