“…It is notable that the formation of 1 proceeded with the amidine-induced cleavage of dinuclear [Pt­(pypm)­(μ-Cl)] 2 . Similar donor-induced dissociation of dimers has been well documented in the literature. …”

“…Two isomers of complexes [Pt­(ppy)­X­( L )] may exist in solution. , Based on the established order of a kinetic trans effect, it would be expected that the halo ligand trans to the carbon donor would be more labile and that the monodentate ligand would be located trans to the carbon. However, the most published cyclometalated platinum complexes [Pt­(ppy)­X­( L )] are presented by cis (N,X) isomers and there are only few representatives of trans (N,X) complexes. To get an idea about the preferred molecular structure of complexes 1 – 8 in solution and to identify spectral features that could be used to analyze their isomeric structures in solution, quantum-chemical (DFT) calculations were carried out. According to the calculations, the cis (N,X) isomer is substantially more preferable in terms of energy than the trans (N,X) isomer (by 8–9 kcal/mol) for both halo ligands (Table S1).…”

“…As a consequence, the donor properties of py 2CF 3 , and hence of the corresponding nitrogen in bpy 6CF 3 , are expected to be poor. A survey of literature data showed only one result for coordination of py 2CF 3 , versus 888 results for py 2CH 3…”

“…As a consequence, the donor properties of py 2CF 3 , and hence of the corresponding nitrogen in bpy 6CF 3 , are expected to be poor. A survey of literature data showed only one result for coordination of py 2CF 3 , 23 versus 888 results for py 2CH 3 . 24 A clue concerning the electronic influence of these substituents on the pyridine ring is also given by comparison of Hammett σ values: CF 3 has a marked electron-attracting effect, both inductive and mesomeric, whereas the opposite effect is provided by CH 3 : σ m (CF 3 ) = +0.43, σ m (CH 3 ) = −0.07; σ p (CF 3 ) = +0.54, σ p (CH 3 ) = −0.17.…”
