%X The complex LW V S(&#181;-S) 2 W V S(S 2 PPh 2 ) &#91;L = tris(3,5-dimethylpyrazol-1-yl)hydroborate&#93; results from the reaction of LW VI O 2 Cl with PPh 3 in refluxing pyridine, followed by the addition of NH 4 S 2 PPh 2 and reflux for a further 4 days. Crystals of LWS(&#181;-S) 2 WS(S 2 PPh 2 )&#183;0.5CH 2 Cl 2 are monoclinic and belong to space group Cc with a 12.356(2), b 30.067(6), c 22.082(4) &#197;, &#946; 96.08(2)&#176; and Z 8. Refinement of 10507 data measured with Mo K&#945; radiation converged at R 0.0466 and R w 0.1421. The two independent molecules in the unit cell are dinuclear with a syn-&#91;W 2 S 2 (&#181;-S) 2 &#93; 2+ core. One tungsten centre is further coordinated by a tridentate L ligand, making it six-coordinate with a distorted octahedral geometry while the other bears a bidentate dithiophosphinate ligand and is five-coordinate and square- pyramidal in geometry. The terminal thio&#8211;tungsten distances average 2.120 &#197;, and the parameters of the core &#91;W&#8211;W av. 2.832 &#197;, W&#8211;(&#181;-S) av. 2.311 &#197;, S&#8211;W&#8211;S av. 100.2&#176;, W&#8211;S&#8211;W av. 75.2&#176;&#93; are typical of syn-&#91;W 2 S 2 (&#181;-S) 2 &#93; 2+ complexes.
