Heterocycles Containing Tungsten, Phosphorus, Sulphur, and Nitrogen in the Ring Skeleton The new ligand Me 2 S(NPPh 2 NSiMe 3 ) 2 ( 2 ), prepared from Me 2 S‐(NPPh 2 ) 2 ( 1 ) and Me 3 SiN 3 , reacts with WF 6 and WCl 6 to form the heterocycles Me 2 S(NPPh 2 N) 2 WF 4 ( 3a ) and Me 2 S(NPPh 2 N) 2 WCl 4 ( 3b ). The X‐ray single‐crystal structure analysis exhibits a puckered eight‐membered ring with alternating short and long bond lengths. 3a crystallizes with one molecule of dimethylformamide in the space group Cc with a = 1247.3(6), b = 1728.5(9), c = 1543.1(8) pm and β = 102.41(3)°.
