Synthesis, spectroscopic (1H, 13C, 31p, 29Si NMR) characterisation and X-ray structure of the first nickel(O) π-complex with vinylcyclosilazane [{Ni(PPh3)}2{μ-(η-CH2=CH(Me) Si(μ-NH))4}] (1a) have been presented. This is the first report on the structure of a TM complex with a vinylsilazane ligand. Complex 1a is synthesised by the reaction of [Ni(cod)2] with cyclotetra (vinylmethylsilazane). The complex occupies a special position of the space group P21/c on the centre of symmetry that lies in the middle of the cyclotetrasilazane ring. The coordination of nickel is close to triangular one.
