“…The molecule possesses a crystallographic inversion symmetry consists of a linear Cp*-W-W-Cp* unit in which the p-bonded Cp* ligands lie perpendicular to the W-W bond. The W-W bond length of 2.6595(5) Å is significantly shorter than in [W 2 (CO) 4 (l-SePh) 6 ], 47 [W 2 (l-S 2 ) 2 Cl 6 (SeCl 2 ) 2 ] 48 and [W 2 (l-S 2 ) 2 (S 2 CNR 2 ) 4 ] 2? .…”

Syntheses and structural elucidations of a series of chalcogen stabilized binuclear complexes of group 5 and 6 transition metals have been described. Room temperature reaction of [Cp*CrCl] 2 (Cp* = g 5-C 5 Me 5) with Li[BH 3 (SePh)] afforded a Se inserted binuclear chromium complex, [(Cp*Cr) 2 (l-Se 2 SePh) 2 ], 1. In an attempt to make the analogous complexes with heavier group 6 metals, reactions of [Cp*MCl 4 ] (M = Mo and W) with Li[BH 3 (SePh)] were carried out that yielded Se inserted binuclear complexes [(Cp*M) 2 (l-Se) 2 (l-SePh) 2 ], 2 and 3 (2: M = Mo and 3: M = W) along with known [(Cp*M) 2 B 5 H 9 ], 4ab (4a: M = Mo and 4b: M = W). Similarly, the reactions of [Cp*NbCl 4 ] with Li[BH 3 (EPh)] (E = S or Se) followed by thermolysis led to the formation of binuclear chalcogen complexes [(Cp*Nb) 2 (l-E 2) 2 ], 5 and 6 (5: E = S and 6: E = Se) and known [(Cp*Nb) 2 (B 2 H 6) 2 ], 7. All these complexes have been characterized by 1 H and 13 C NMR spectroscopy and mass spectrometry. The structural integrity of complexes 1, 3, 5 and 6 was established by the X-ray diffraction studies. The DFT studies further exemplify the bonding interactions present in these complexes, especially the multiple bond character between the metals in 1-3.

Mono‐ and bis(trichlorostannyl) complexes [MCl(SnCl3)(η5‐C5Me5){P(OR)3}] (1, 2) and [M(SnCl3)2(η5‐C5Me5){P(OR)3}] (3, 4) (M = Rh, Ir; R = Me, Et) were prepared by allowing chloro compounds MCl2(η5‐C5Me5)[P(OR)3] to react with anhydrous SnCl2 in refluxing 1,2‐dichloroethane. Treatment of trichlorostannyl complexes of iridium 2 and 4 with NaBH4 in ethanol afforded hydride‐trihydridestannyl derivatives [IrH(SnH3)(η5‐C5Me5){P(OR)3}] (5) and bis(trihydridestannyl) [Ir(SnH3)2(η5‐C5Me5){P(OR)3}] (6), the reaction of which with methylpropiolate HC≡CCOOMe led to trivinylstannyl derivatives [IrH{Sn[C(COOMe)=CH2]3}(η5‐C5Me5){P(OMe)3}] (7 a) and [Ir{Sn[CH=C(H)COOMe]3}2(η5‐C5Me5){P(OMe)3}] (8 a). The complexes were characterised spectroscopically (IR and 1H, 31P, 13C, 119Sn NMR) and by X‐ray crystal structure determination of [Ir(SnCl3)2(η5‐C5Me5){P(OMe)3}] (4 a).
