The imine complexes W(PhC≡CPh)3(NH=C(Me)2) (1) and W(PhC≡CPh)3(NH=C(Ph)Me) (2) have been prepared by sequential treatment of W(PhC≡CPh)3(NCMe) with MeLi and PhLi, respectively, and H2O. However, treating W(PhC≡CPh)3(NCMe) with LiHBEt3 and H2O in sequence produces the amine complex W(PhC≡CPh)3(NH2Et) (3). Similar treatment of W(η4-C4Ph4)(PhC≡CPh) 2(NCMe) with LiHBEt3/H2O and PhLi/H2O yields W(η4-C4-Ph4)(PhC≡CPh) 2(NH2Et) (4) and W(η4-C4Ph4)(PhC≡CPh) 2(NH=C(Ph)Me) (5), respectively. Compound 1 crystallizes in space group P21/c with a = 10.075(2) A?, b = 10.474(3) A?, c = 32.906(7) A?, β = 94.88(2)°, V = 3460(1) A?3, Z = 4, and RF = 0.026.
