Square-Planar Pd(II), Pt(II), and Au(III) Terpyridine Complexes: Their Syntheses, Physical Properties, Supramolecular Constructs, and Biomedical Activities

“…Dimorphism of [Pt(tpy)(Cl)][Cl], which was crystallized in a yellow colored form from EtOH and a less-stable red form from 1 M HCl, was detected Via X-ray powder diffraction. 110 …”

A Polymorphic Platinum(II) Complex: Yellow, Red, and Green Polymorphs and X‐ray Crystallography of [Pt(fdpb)Cl] [Hfdpb = 1,3‐Bis(5‐trifluoromethyl‐2‐pyridyl)benzene]

“…[7][8][9] Many Pt II complexes have been found to show dimorphism, which is dependent on the molecular arrangement in the crystal. [10][11][12][13] The color of the crystal is easily changed by environmental stimuli such as the application of pressure, exposure to organic solvent vapor, or mechanical grinding. Pressure-induced redshifts of the emission band have been reported for square-planar Pt II complexes.…”

A novel linear-chain material showing sandwiched stacking via alternative Pt(II)⋯Pt(II) or Pt(II)⋯S and π⋯π interactions

“…Thus, 1 features a novel linear-chain material showing sandwiched stacking via alternative Pt(II)Á Á ÁPt(II) or Pt(II)Á Á ÁS interactions, where the pÁ Á Áp interactions propagate in the whole chain structure. Indeed, 1 can also be regarded as a consequence of intercalating [Pt(8-QNS) 2 ] [11] into a linear-chain [Pt(terpy)Cl]ClO 4 [12]. This is reminiscent of the delicate work carried out by Bosnich and co-workers [13] regarding the molecularrecognition study on the structural and spectroscopic properties of double-clipped Pt(II)-or Pd(II)-terpy complexes.…”
