Summary Mixed ligand complexes of the type Ni(R-AB)(AC′) and Ni(R-AC)(AB′) where AB/AC denote N-bonded isonitrosoβ-ketoimino ligands, AB′/AC′ denote the corresponding O-bonded ligands and R=Me, Et, n-Pr are synthesised and characterised. The complexes are neutral with square planar geometry around nickel(II). The bonding isomerism of the isonitroso group is discussed on the basis of i.r. and1H n.m.r. studies. The crystal structure of the title complex, Ni(n-Pr-IEAI)(IMAI′) has been determined from diffractometer data by Patterson and Fourier methods and refined by least squares to R=0.088 for 2209 observed reflections. Unit cell constants are: a=11.945(2), b=22.436(7), c=13.248(5) Å, β=95.13(2)°. The space group is P21/c with Z=8. Nickel(II) has a square planar coordination of two imine nitrogens, an isonitroso-nitrogen (from n-Pr-IEAI) and another isonitrosooxygen (from IMAI′).
