Abstract

The Ti(III) azido complex (PN)<inf>2</inf>Ti(N<inf>3</inf>) (PN<sup>-</sup> = (N-(2-(diisopropylphosphino)-4-methylphenyl)-2,4,6-trimethylanilide), can be reduced with KC<inf>8</inf> to afford the nitride salt [μ<inf>2</inf>-K(OEt<inf>2</inf>)]<inf>2</inf>[(PN)<inf>2</inf>Ti≡N]<inf>2</inf> in excellent yield. While treatment of the dimer with 18-crown-6 yields a mononuclear nitride, complete encapsulation of the alkali metal with cryptand provides the terminally bound nitride as a discrete salt [K(2,2,2-Kryptofix)][(PN)<inf>2</inf>Ti≡N]. All complexes reported here have been structurally confirmed and also spectroscopically, and the Ti-N<inf>nitride</inf> bonding has been probed theoretically via DFT-based methods.
