“…Iodine itself and polyiodide species are useful models for studies of weak interactions (for instance, XB and HB), and an appropriate CAS SciFinder search indicates a substantial recent growth of their popularity. The identification of the semicoordination bond M•••I including I − has been reported, e.g., for copper(II) complexes (semicoordination bond), 58,59 (amino)copper(II) complexes (elongated bonds as an effect of the Jahn−Teller distortion), 60 and lead(II) species (also formulated as tetrel bonding). 61 Notably, this shows that the semicoordination bond that involves polyiodide anions I n − (n = 3, 5, etc.)…”

Reinvestigation of (o-benzoquinonedioximate)2Ni/I2 systems demonstrated that the reaction itself and also the crystallization conditions dramatically affect the identity of generated species. Crystallization (CHCl3, 20–25 °C) of the nickel(II) dioximate complex [Ni(bqoxH)2] (bqoxH2 = o-benzoquinonedioxime) with I2 in the 1:(1–10) molar ratios of the reactants led to several (o-benzoquinonedioximate)2Ni derivatives and/or iodine adducts [Ni(I)(bqoxH)(bqoxH2)]·3/2I2, [Ni(I3)(bqoxH)(bqoxH2)]·[Ni(bqoxH)2], and [Ni(I3)(bqox•–)(bqoxH2)]·I2; the latter one, featuring the anion-radical bqox•– ligand, is derived from the formal (−2H+/1e –)-oxidation of bqoxH2. In these three adducts, various types of noncovalent interactions were identified experimentally and their existence was supported theoretically. The [Ni(I3)(bqox•–)(bqoxH2)]·I2 adduct exhibits simultaneous semicoordination and coordination patterns of the triiodide ligand; this is the first recognition of the semicoordination of any polyiodide ligand to a metal center. The semicoordination noncovalent contact Ni···I3 (3.7011(10) Å) is substantially longer that the Ni–I3 coordination bond (2.8476(9) Å), and the difference in energies between these two types of linkages is 8–12 kcal/mol.
