Bluish-white luminescence

Thus, pure samples of the complex formed crystals with varying luminescence. Most of the crystals exhibited the described yellow luminescence, but others displayed a bluish-white luminescence and a few of the crystals showed a pink luminescence. The two new forms of trinudear complex can be obtained by evaporation of dichloromethane solutions of the complex. They consisted of one triclinic form and one monoclinic form and both crystallized as colorless blocks, in contrast to the results with the original solvoluminescent hexagonal form that crystallized as colorless needles. These polymorphs differed in the packing of the nearly planar molecules and in the nature of the aurophilic interactions between the trinudear units (see Figure 6.16).
