Large pressure-induced red shift of the luminescence band originating from nonstacked square-planar [Pt(SCN)(4)](2-) in a novel trimetallic complex
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.
