Cis Isomer

The relative stability of the trans and cis isomers in the square planar palladium(II) complexes Pd ( I )( PPh 3)(η3- XCHC ( Ph ) CHR ) ( X = H , Me , CMe 3, CO 2 Me , P ( O )( OMe )2, and SO 2 H ; R = H , Me ) was investigated with the aid of the B3LYP density functional theory calculations. We examined how the substituents X, with different electronic properties, of the η3-allyl ligands affect the relative stability of the trans and cis isomers. Through the investigation, we were able to explain the trans/cis relative stability derived from the experimentally measured trans/cis isomer ratios in the palladium(II) complexes.

New vanadate photocatalysts, Ag2Sr(VO3)4 and Sr(VO3)2, are theoretically designed for water oxidation reactions. The calculations have shown that the new photocatalysts possess desirable electronic structures. Our experiments demonstrated that these vanadates efficiently oxidize water to O2 under irradiation of visible light.
