Abstract

Several group 15 compounds of the type EAr(3) (Ar = 2-[(dimethylamino)methyl]phenyl; E = As (4), Sb (5), Bi (6)) have been prepared via salt elimination reactions of 2-(Me(2)NCH(2))C6H4Li and ECl(3). Treatment of the lithium salt of the 8-(dimethylamino)-1-naphthyl ligand (Ar') with AsCl3 afforded a triaryl derivative, AsAr'(3) (7). The X-ray crystal structures of 4-7 are described, and the observed trends in the degree of intramolecular coordination of the nitrogen atoms are discussed. Crystal data for 4: monoclinic, space group P2(1)/c, a = 8.9336(6) Angstrom, b = 16.347(2) Angstrom, c = 17.875(2) Angstrom, beta = 102.540(7)degrees, V = 2548.2(4) Angstrom, Z = 4, R = 0.0579. Crystal data for 5: monoclinic, space group P2(1), a = 9.288(2) Angstrom b = 18.356(4) Angstrom c = 15.566(2) Angstrom, beta = 90.28(2)degrees, V= 2654.1(8) Angstrom(3), Z = 4, R = 0.0520. Crystal data for 6: monoclinic, space group P2(1), a = 9.2996(12) Angstrom, b = 18.445(3) Angstrom, c = 15.601(2) Angstrom, beta = 90.076(11)degrees, V = 2676.1(7) Angstrom(3), Z 3 4, R = 0.0783. Crystal data for 7: monoclinic, space group P2(1)/c, a = 9.5744(12) Angstrom, b = 16.273(2) Angstrom, c = 18.884(3) Angstrom, beta = 100.708(11)degrees, V = 2890.9(7) Angstrom(3), Z = 4, R = 0.0495.
