Popis:	Reaction between Os(SnI3)(κ2-S2CNMe2)(CO)(PPh3)2 and NaBH4 produces the unusual, air-stable, trihydridostannyl complex, Os(SnH3)(κ2-S2CNMe2)(CO)(PPh3)2 (1), which has been fully characterised including by X-ray crystal structure determination.Similarly, reaction between Os(SnI2Me)(κ2-S2CNMe2)(CO)(PPh3)2 or Os(SnClMe2)(κ2-S2CNMe2)(CO)(PPh3)2 and NaBH4 produces the dihydridostannyl complex, Os(SnH2Me)(κ2-S2CNMe2)(CO)(PPh3)2 (4) or the monohydridostannyl complex, Os(SnHMe2)(κ2-S2CNMe2)(CO)(PPh3)2 (6), respectively.The Sn H bonds in these complexes are reactive towards acids and in selected reactions complexes 1 and 4 with aqueous HF give Os(SnF3)(κ2-S2CNMe2)(CO)(PPh3)2 (3) and Os(SnF2Me)(κ2-S2CNMe2)(CO)(PPh3)2 (5), respectively, and complex 6 with aqueous HCl gives Os(SnClMe2)(κ2-S2CNMe2)(CO)(PPh3)2.The trihydridostannyl complex 1 reacts with chloroform to form the trichlorostannyl complex, Os(SnCl3)(κ2- S2CNMe2)(CO)(PPh3)2 (2). The crystal structures of 1–3, 5, and 6 have been determined.
