Ethyldimethylphenylammonium-halogenoantimonates(III)

Abstract

The compounds were prepared by reaction of SbX3 with EtMe2PhNX (X = Cl, Br, I) in ethanol. Single crystal structure determinations yielded at room temperature: [EtMe2PhN](4)Sb4Cl16 1 S.G. P2(1)/n, No. 14, a=1234.1(2), b=1299.8(2), c=1985.9(5)pm, beta=96.81(2)degrees and Z=2; [EtMe2PhN](3)[Sb2Br9], 2, S.G. Pnma, No. 62, a = 3562.0(7), b = 995.4(2), c = 1276.1(3) pm and Z = 4; [EtMe2PhN](4)[Sb6I22], 3, S.G. P (1) over bar, No.2, a=1146.3(3), b = 1223.1(2), c = 1743.7(3) pm, alpha = 88.25(2)degrees, beta = 87.33(2)degrees, gamma = 67.09(2)degrees and Z = 2. Enthalpies of transition and melting were determined with a DSC.
