A theoretical study of the interactions of NF3 with neutral ambidentate electron donor and acceptor molecules

Abstract

A theoretical study of the complexes (dimers and trimers) formed between nitrogen trifluoride (NF₃) and the ambidentate electron donor/acceptor systems HF, FCl, HCN, and HNC has been carried out using DFT [M05-2x/6-311++G(d,p)] and ab initio methods [(MP2/6-311++G(d,p) and MP2/aug-cc-pVTZ)]. Due to its structure, the NF₃ molecule can interact with both electron acceptors and electron donors through its N and F atoms. Thus, five minimum energy structures have been located for the dimers and four minima structures have been studied for the trimer complexes. New σ-hole bonding complexes have been located.
