摘要：

The dimetallic complex, (CO)(5)W(mu-PPh(2)CH(2)PPh(2))W(CO)(5), is synthesized from either a 2:1 mixture of (CO)(5)W(NCMe) and (CO)(5)W(eta(1)-PPh(2)CH(2)PPh(2)) or a 3:1 mixture of (CO)(5)W(NCMe) and PPh(2)CH(2)PPh(2) in toluene at 60 degrees C. The coupling constants, (2)J(PP') = 22.9 Hz, (1)J(WP) = 246.9 Hz and (3)J(WP') = 4.5 Hz are consistent with those reported in the literature for similar complexes. The complex (CO)(5)W(eta(1)-PPh(2)CH(2)PPh(2)) is stable with respect to chelation at room temperature.
