Abstract

One equivalent of [Na2(thf)5-(P4Ph4)] (1) reacts with one equivalent of [Ni(cod)2] (cod=1,5-cyclooctadiene) to give the unexpected ionic compound [Na(Et2O)3][Na3(Et2O)2Ni3(micro-P2Ph2)2-(P2Ph2)3] (2), whereas the reaction of [Ni(cod)2] with the less reactive [K2(pmdeta)2(P4Ph4)] (3) leads to the formation of [K(pmdeta)]2[Ni(P4Ph4)-(P2Ph2)] (4) (PMDETA=NMe(CH2CH2NMe2)2), in which K--Ni interactions are observed. The calculations for 4 confirm the structural parameters obtained by X-ray diffraction studies. A shared electron number (SEN) analysis was applied to investigate the K...Ni interactions. These studies indicate a SEN value of a typical three-center, two-electron bond for K1-Ni-K2 indicating a covalent contribution in the interaction between nickel and potassium.
