Crystal structure of cis-[1,2-bis(diphenylphosphanyl)ethene-κ² P,P′]dichloridoplatinum(II) chloroform disolvate: a new polymorph

Abstract

A third monoclinic polymorph of the title compound is described. In the crystal, it exhibits C—H⋯Cl hydrogen bonds and face-on Cl⋯π inter­actions involving the chloro­form disolvate mol­ecules. Inter­molecular weak offset π–π inter­actions are also present between the aromatic rings of the ligands.

A mixed phosphine sulfide/selenide structure as an instructional example for how to evaluate the quality of a model

“…Our research group has synthesized a number of phosphine chalogenide derivatives and explored their chemistry in regard to their coordination with both d-block and f-block metals (Luster et al, 2022;Mugemana et al, 2018;Morse et al, 2016;Neils et al, 2022). A few years ago, we worked with the rigid diphosphine cis-1,2-bis(diphenylphosphine)ethylene 1 (cisdppe), and developed conditions for the synthesis of the disulfide 2 (Rawls et al, 2023) and the di-selenide 3 (Jones et al, 2015) (Fig.…”
