Abstract

original image

A lengthening of the Ni[BOND]Ni bonds (from 251–269 to 277–285 pm) is observed when a Ni atom is incorporated into Ni8 cluster. This is shown by the X-ray structural analysis of 1, which is formed (together with 2, a little nickel and further unidentified complexes) from [NiCl2(PPh3)2] and PhAs(SiMe3)2. In contrast, the bonds to the interstitial Ni atom are considerably shorter: Ni[BOND]Ni(Cl) 245–248, Ni[BOND]Ni(PPh3) 238–242 pm, equation image
