Abstract
Colourless single crystals of [Ph3PNH2(OEt2)][Sm(NCS)(4)(DME)(2)] (1) havebeen obtained besides of Ph3PS from the reaction of the homoleptic phosphorane iminato complex [Sm(NPPh3)(3)](2) with carbon disulfide in THF solution, followed by recrystallisation from DME/Et2O. According to the crystal structure analysis 1 consists of [Ph3PNH2](+) cations with the diethylether molecule forming a N-H . . .O hydrogen bridge, and anions [Sm(NCS)(4)(DME)(2)](-). Sm3+ realizes coordination number eight by four nitrogen atoms of the isothiocyanato ions and by four oxygen atoms of the DME chelates.1: Space group P(1) over bar, Z = 4, lattice dimensions at 193 K: a = 919.0(1), b = 1965.2(2), c = 2401.3(2) pm, alpha = 96.748(11)degrees, beta = 94.827(10)degrees, gamma = 91.720(11)degrees, R = 0.029.
