Abstract

The neutral bisimidoylamidine (or 1,3,5‐triazapentadiene) Ni^II^ complexes [Ni{H__N__C(R)NC(C~6~H~4~CO)N}~2~] {R=Me, Et, __n__Pr, __i__Pr, (CH~2~)~3~Cl}, bearing an iminoisoindolinone moiety, have been generated by a novel 2‐propanone oxime‐mediated single‐pot reaction of phthalonitrile and nickel(II) acetate in solution of the corresponding alkylnitrile (RCN). Single‐crystal X‐ray diffraction analyses indicate a square‐planar geometry of the imidoylamidine core. The synthesised compounds represent rare specimens of genuine unsymmetrical imidoylamidine complexes as well as their first examples generated from nitriles in a single‐pot reaction.
