Abstract
Density Functional Theory studies of square‐planar PtII pincer structures, (4‐Z‐NCN)PtCl ([4‐Z‐NCN]−=[4‐Z‐2,6‐(Me2NCH2)2C6H2‐N,C,N]−, Z=H, NO2, CF3, CO2H, CHO, Cl, Br, I, F, SMe, SiMe3, tBu, OH, NH2, NMe2), enable characterisation of mesomerism for the pincer‐Pt interaction. Relationships between Hammett σp substituent parameters of Z and DFT data obtained from NBO6 and AOMix computation are used to probe the interaction of the 5dyz orbital of platinum with π‐orbitals of the arene ring. Analogous computation for 2,6‐(Me2CH2)2C6H3Z (Z=H, CF3, CHO, Cl, Br, I, F, SMe, SiMe3, tBu, OH, NH2) and (4‐H‐NCN)PtZ allows an estimation of the relative substituent effects of "(CH2NMe2)2PtZ" on π‐delocalisation in the pincer system.
