title: Large pressure-induced red shift of the luminescence band originating from nonstacked square-planar [Pt(SCN)4]2- in a novel trimetallic complex.
abstract: Luminescence of the novel trimetallic complex {Pt(SCN)2[(mu-SCN)Mn(NCS)(bipy)2]2} originates from a d-d transition of the square-planar [Pt(SCN)4]2- moiety. The band maximum shows a red shift of -99 cm(-1) kbar(-1) under external pressure up to 32 kbar at room temperature. This red shift is comparable to values for crystals where Pt-Pt interaction between stacked complexes is enhanced by pressure, but the crystal structure for the trimetallic complex shows that no metal-metal interaction can occur.
