N2 - The coordination chemistry of Ni II supported by (E)-N′-(1-(thiophen-2-yl)ethylidene)benzohydrazide ligand (HL) is reported and discussed. The crystal structure of ligand HL has been determined as well as those of three new Ni II complexes (Ni(HL) 2Br 2, NiL 2 and μ-aquo-Ni 2L 4). The pseudo-octahedral bis(chelate) Ni(II) complex 2 (NiL 2), in which unexpected and singular Ni⋯S interaction is observed, was evaluated as catalyst for the oligomerization of ethylene and found to provide ethylene dimers and trimers as primary products with a turnover frequency (TOF) of 31 200 mol of C 2H 4 per mol. of Ni and per hour.
