Yl. Zhou et al., THE PREPARATION AND CHARACTERIZATION OF SQUARE-PLANAR TETRAKIS(CYANOACETYLIDE) COMPLEXES - [M(II)(C-C-C-N)(4)](2-) (M=NI, PD, PT), Chemical communications, (16), 1996, pp. 1881-1882
Complexes [M(II)(C=C=C=N)(4)](2-) (M = Ni, Pd, Pt) are prepared for th
e first time and the structure of [NEt(4)](2)[Ni(C=C=C=N)(4)] is deter
mined to have a square-planar geometry.
