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.

Ground State Structures

Geometric structure of Osn(n=2-10) clusters are optimized by using Density functional theory (DFT) in DMOL3 package. For the ground-state structure, relative stability are analyzed. The results show that: the ground-state structures of the cluster are plane structure when n=2-4, but the ground-state structures are stereostructure when n≥5. There exhibits the odd-even oscillation effect in stability and Os8cluster has the highest stability.
