Crystal Structure of the Isothiocyanato Complex [Ph 3 PNH 2 (OEt 2 )][Sm(NCS) 4 (DME) 2 ] Colourless single crystals of [Ph 3 PNH 2 (OEt 2 )][Sm(NCS) 4 (DME) 2 ] ( 1 ) have been obtained besides of Ph 3 PS from the reaction of the homoleptic phosphorane iminato complex [Sm(NPPh 3 ) 3 ] 2 with carbon disulfide in THF solution, followed by recrystallisation from DME/Et 2 O. According to the crystal structure analysis 1 consists of [Ph 3 PNH 2 ] + cations with the diethylether molecule forming a N–H…O hydrogen bridge, and anions [Sm(NCS) 4 (DME) 2 ] – . Sm 3+ 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, Z = 4, lattice dimensions at 193 K: a = 919.0(1), b = 1965.2(2), c = 2401.3(2) pm, α = 96.748(11)°, β = 94.827(10)°, γ = 91.720(11)°, R = 0.029.
