- New coordination motives at cyclothiazeno complexes of molybdenum and tungsten. Crystal structures of [{Mo(N3S2)(Cl)(OtBu)2}{Mo(O)(N 3S2)(OtBu)}]2 and [W(N3S2)2(LiCl){N=W(NPPh3) 3}2]

The metalla cyclothiazeno complexes (Cyclo-1λ6-metalla-3,5-dithia-2,4,6-triazino complexes) [{Mo(N3S2)(Cl) · (OtBu)2}{Mo(O)(N3S2)(O tBu)}]2 (1) and [W(N3S2)2(LiCl) · (N≡W(NPPh3)3}2] (2) are formed from [MoCl3(N3S2)]2 and LiOtBu in toluene, and from [WCl3(N3S2)]2 and LiNPPh3 in THF, respectively. The complexes form moisture sensitive, black (1) or brown (2) crystals, which we characterized by crystal structure analyses. 1 · Toluene: Space group P1, Z = 1, lattice dimensions at -83 °C: a = 934.2(1), b = 964.4(1), c = 1700.3(1) pm; α = 83.54(1)°, β= 78.35(1)°, γ = 71.56(1)°, R1 = 0.0339. 2 · 1.625 Toluene · 0.75 THF: Space group P1, Z = 4, lattice dimensions at -80°C: a = 1313.8(1), b = 2896.8(2), c = 3384.9(3) pm; α= 82.42(1)°, β= 88.71(1)°, γ = 77.28(1)°, R1 = 0.0603.
