Crystal Structures of Bu4N[Pt(ppy)Cl2], Et4N[Pt(tpy)Cl2] and [Pt(ppy)en]Cl (ppy = N,C'-Chelated 2-Phenylpyridinate, tpy = N,C'-Chelated 2-(2'-Thienyl)pyridinate, en = N,N'-Chelated 1,2-Diaminoethane).

Thermo‐ and Mechano‐Triggered Luminescence ON/OFF Switching by Supercooled Liquid/Crystal Transition of Platinum(II) Complex Thin Films

“…Although square‐planar Pt(II) complexes tend to assemble based on Pt–Pt and/or π–π interactions, [ 3 ] bulky Bu 4 N + cations prevent such interactions to afford the “discrete” nature. [ 2d,15 ] Likewise, the photophysical measurements indicated the discrete environments for all the Pt(II) complexes (not only 1‐Cl and 1‐Br, but also 2‐Cl and 2‐Br) in their crystal phases (vide infra), although it was difficult to conduct the X‐ray crystallographic analysis of 2‐Cl and 2‐Br.…”

Platinum organometallic compounds: classification and analysis of crystallographic and structural data. Part I. Monomeric Pt(0) and partly of Pt(II) with PtC4, PtA3B and PtC2A2 chromophores

“…There are nine yellow derivatives (Growe et al 1986, Constable et al 1990, Chan et al 1993, Kwam et al 1996, Jenkins et al 1997, Abbietz et al 1999 in which three N atoms with a C atom create a square planar environment about each Pt(II) atom; however, there is no example with only monodentate ligands. In one (Abbietz et al 1999 ), a bidentate ar 2 dab-N , N ′ with MeCN and methyl ligand give the PtN 3 C chromophore.…”

“…In one (Abbietz et al 1999 ), a bidentate ar 2 dab-N , N ′ with MeCN and methyl ligand give the PtN 3 C chromophore. In another derivative (Kwam et al 1996 ), a bidentate ethylenediamine-N , N ′ with a bidentate 2-phenylpyridinate-C,N creates the same chromophore about Pt(II) atom. Both form a fi ve-metallocyclic ring, with N − Pt − N and C − Pt − N bite angles of 82.3(2) ° and 80.7(2) ° , respectively.…”

Cleavage of the Pt-I bond in a Primary Cycloplatinated Amine by Chelation

“…The Cambridge Crystallographic Database [7] contains 295 structures in which ethylenediamine acts as a chelating ligand for Pt, and only two of these involve tertiary cycloplatinated amines [5] or imines [6]. No cycloplatinated primary or secondary amines containing ethylenediamine have been reported to date.…”

“…In this contribution, we communicate the substitution of both monodentate ligands, σ donor amine and iodo substituent by the well-known chelating ligand ethylenediamine, and we report the crystal structure of the resulting ionic product. Organoplatinum (II) complexes of ethylenediamine derived from substituted rather than primary amines have been published by Kvam et al [5] and Failes et al [6].…”
