A platinum(II) complex Pt(DiBrbpy)Cl2(1) based on 4,4′‐dibromo‐2,2′‐bipyridine ligand was synthesized and characterized. Interestingly, two solvated phases of1with different amounts of crystalline CH2Cl2molecules,1·1/3(CH2Cl2) (yellow) and1·3/2(CH2Cl2) (red), were obtained. In the solid state,1·1/3(CH2Cl2) exhibits a 3D supramolecular structure based on Pt(DiBrbpy)Cl2monomer and emits a weak yellow luminescence at 541 nm (579, sh). In contrast,1·3/2(CH2Cl2) displays a 2D layer structure based on Pt(DiBrbpy)Cl2dimeric units and has a strong red luminescence centered at 624 nm. The results show that crystalline solvate molecule amount can not only influence the packing structures but also photophysical properties of the platinum moiety in solid state. Furthermore, the absorption and luminescence spectra of both phases were studied by TD‐DFT calculations.
