Formula Unicode styled:
[W(Cl)₂(NPh₂)₂(Bpy)]
Compound name(s):
(Bipyridyl-N,N')-dichloro-bis(phenylimido-N)-tungsten
Central atom:
Charge on formula unit (QN):
0
Attached groups:
Compound type:
Notes:
At first sight this is an 16-electron compound (EN=16). However the two NPh groups are planar and each has an out-of-plane p-orbital. These engage in a π-type interaction with the metal to form an extra bond classified as L-type (2-electrons). This takes the overall electron number (EN) to 18.
