| Abstract |
Two silver(I) complexes were obtained by the reaction of a N-6 ligand with [Ag(PPh3)(2)(MeCN)](SbF6). In complex [AgL1(PPh3)](SbF6) 1, the silver center is bound to three N donors of the nitrogen ligand and P donor of one triphenylphosphine group, forming an irregular AgN3P tetrahedron. In complex [Ag(PPh3)(4)](SbF6) 2, the Ag+ ion is coordinated to four triphenylphosphine groups, affording a tetrahedral geometry. Crystal data for complex 1: C30H37AgF6N6PSb, M-r = 856.25, orthorhombic, space group Pbca, a = 19.0702(9), b = 15.9047(7), c = 21.498(1) Angstrom, V = 6520.5(6) Angstrom(3), Z = 8, D-c = 1.744 g/cm(3), F(000) = 3408, mu = 1.544 mm(-1), the final R = 0.0367 and wR 0.1077 for 5325 observed reflections with I > 2sigma(I); and those for 2: C72H60AgF6P4Sb, M-r = 1392.70, trigonal, space group R \$(3) over bar \$ a = 14.4577(6), b = 14.4577(6), c = 51.544(2) Angstrom, V = 9330.5(7) Angstrom(3), Z = 6, D-c = 1.487 g/cm(3), F(000) = 4224, mu = 0.913 mm(-1), the final R = 0.0352 and wR = 0.1089 for 3498 observed reflections with I > 2sigma(I). |
