新的三金属配合物{Pt（SCN）2[（mu-SCN）Mn（NCS）（bipy）2]2}的发光源于正方平面[Pt（SCN）4]2-部分的d-d跃迁。在室温下，当外压高达32 kbar时，谱带最大值红移为-99 cm（-1）kbar（-1）。该红移与其中堆叠的络合物之间的Pt-Pt相互作用通过压力增强的晶体的值相当，但是三金属络合物的晶体结构显示不可能发生金属-金属相互作用。
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.
