Author is Bulatov, Evgeny; Eskelinen, Toni; Ivanov, Alexander Yu.; Tolstoy, Peter M.; Kalenius, Elina; Hirva, Pipsa; Haukka, Matti.

Coordination compounds of platinum(II) participate in various noncovalent axial interactions involving metal center. Weakly bound axial ligands can be electrophilic or nucleophilic; however, interactions with nucleophiles are compromised by electron d. clashing. Consequently, simultaneous axial interaction of platinum(II) with two nucleophilic ligands is almost unprecedented. Herein, the authors report structural and computational study of a platinum(II) complex possessing such intramol. noncovalent I···Pt···I interactions. Structural anal. indicates that the two iodine atoms approach the platinum(II) center in a side-on fashion and act as nucleophilic ligands. According to computational studies, the interactions are dispersive, weak and anti-cooperative in the ground electronic state, but strengthen substantially and become partially covalent and cooperative in the lowest excited state. Strengthening of I···Pt···I contacts in the excited state is also predicted for the sole previously reported complex with analogous axial interactions.
