5-Cyclopentadienyl){[3-(2,2-dicyanoethenyl)bicyclo[2.2.1]hepta-2,5-dien-2-yl]ethynyl}(triphenylphosphine)nickel(II)Abstract: The title compound, [Ni(C5H5)(C13H7N2)(C18H15P)] or (5-C5H5)(PPh3)Ni-C![[triple bond]](/logos/entities/z-tbnd_rmgif.gif)
C-C7H6-C(H)=C(CN)2, contains an unusual disubstituted norbornadienyl (NBD) ligand containing ethynyl (-CC-) and dicyanovinyl [-C(H)=C(CN)2] groups. Disorder is present in the NBD group with site occupancies of 0.636 (10) and 0.364 (10) for two distinct orientations. There are no strong hydrogen bonds and the primary interactions are weak C-H
