The title compound, [Ni(C15H24NSi)2], is a homoleptic metal–η3-azaallyl centrosymmetric complex containing two azaallyl ligands bound in an η3-manner to an NiII atom located on a center of symmetry. The overall coordination about the NiII atom is square-planar. The C and N atoms of the azaallyl group are sp2-hybridized. The uneven Ni—C and Ni—N distances [2.045 (5)/2.060 (6) and 1.916 (5) Å] are influenced by a steric hindering effect from the nearby benzene ring.
