Modeling cis/trans preferences of Sn("acac")2Cl2 complexes

Presenter(s)

Luke Rising, Hanna Sunsdahl, Matthew Burrows, and Juan Carlos Feregrino Ponce

Abstract

Tin(IV) complexes bearing two chloride ligands and two symmetric β-diketonate ligands exhibit octahedral geometries. As such, they can theoretically present in two geometric isomer forms, cis and trans. Modeling of isomeric forms of these Sn(IV) complexes with five different β-diketonate ligands has been conducted to identify overall preference as well as to attempt to ascertain any influence the ligand's own electronic properties has on exhibited isomeric preference. Additionally, modeled IR spectra of cis and trans forms were compared to determine the utility of that characterization method in distinguishing these isomers.
