Abstract

The reaction of 1,3-bis(diphenylphosphinyl)propane (dpppO 2 ) with MnI 2 , depending on the reactants ratio, affords either 1D coordination polymer, [Mn(dpppO 2 )I 2 ] n ( 1 ), or cage-like complex [Mn 2 (dpppO 2 ) 4 I 2 ]l 2 ( 2 ). Polymer 1 contains Mn(II) ions in a tetrahedral [Mn@O 2 I 2 ] arrangement, while the metal ions of 2 feature a square-pyramidal [Mn@O 4 I] geometry. At ambient temperature, 1 emits green phosphorescence (λ max = 530 nm) with unusually short lifetime being 50 µs, while 2 displays long-lived red phosphorescence with λ max = 660 nm and the lifetime of 1400 µs.

Keywords: Mn(II) complexes, Luminescence, phosphine oxide ligands, Coordination polymers, phosphorescence
