Synthesis, characterization, thermal studies, and DFT calculations on Pd(II) complexes containing N-methylbenzylamine

This work describes the synthesis, characterization, and the thermal behavior investigation of four palladium(II) complexes with general formulae [PdX(2)(mba)(2)], in which mba = N-methylbenzylamine and X = OAc(-) (1), Cl(-) (2), Br(-) (3) or I(-) (4). The complexes were characterized by elemental analysis, infrared vibrational spectroscopy, and (1)H nuclear magnetic resonance. The stoichiometry of the complexes was established by means of elemental analysis and thermogravimetry (TG). TG/DTA curves showed that the thermodecomposition of the four complexes occurred in 3-4 steps, leading to metallic palladium as final residue. The palladium content found in all curves was in agreement with the mass percentages calculated for the complexes. The following thermal stability sequence was found: 3 > 2 > 4 > 1. The geometry optimization of 1, 2, 3, and 4, calculated using the DFT/B3LYP method, yielded a slightly distorted square planar environment around the Pd(II) ion made by two anionic groups and two nitrogen atoms from the mba ligand (N1 and N2), in a trans-relationship.

Pós-graduação em Comunicação Estratégica: uma contribuição multidisciplinar na busca da capacitação organizacional e do compartilhamento de significados entre universidade e mercado

The present study scores postures, approaches and themes to permeadt discussions and the process of construction of Course Specialization of communication at the Faculty of architecture, arts and communication (FAAC) of Universidade Estadual Paulista (UNESP), Bauru, SP, highlighting the difficulties and the paths chosen in search of professional qualification together organizations. Presentation the investigative process, market over demands from the perspective of organizational communication, to try to understand the multidimensional abilities that the course should provide. Finally, it establishes some modules and thematic for the course, intending to reflect the diversity of communicative functions, which are in the highest capacity of human beings, that is to create your reality and interfere in the direction of society.
