A theoretical study of the complexes (dimers and trimers) formed between nitrogen trifluoride (NF(3)) 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 NF(3) 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.
采用 DFT [M05-2x/6-311++G(d,p)] 和从头算方法 [(MP2/6-311++G(d,p) 和 MP2/aug-cc-pVTZ)] 对三氟化氮 (NF(3)) 与双齿电子给体/受体体系 HF、FCl、HCN 和 HNC 形成的配合物(二聚体和三聚体)进行了理论研究。由于 NF(3) 分子的结构,它可以通过其 N 和 F 原子与电子受体和电子供体相互作用。因此,已经确定了二聚体的 5 个最低能量结构,并且研究了三聚体配合物的 4 个极小值结构。已经定位了新的 σ-hole 键合配合物。
