Abstract

The molecular and electronic structures of XCCP molecules, with X = H, F, Cl, Br and I, were investigated using both unrestricted and restricted CCSD(T), CASSCF/CASPT2 and B3LYP methods, with basis sets up to 6-311++G(3df,2p) and cc-pVTZ. Our results indicate that these molecules possess two distinct types of electronic structure, namely phosphinidene and carbene. The triplet phosphinidene is clearly favoured over the singlet carbene. In the ethynyl-phosphinidene (X–CC–P) framework, both triplet and open-shell singlet states feature a linear geometry (3Σ−); the corresponding singlet–triplet energy gaps vary from 70 to 80 kJ mol−1. Except for the closed-shell singlet of HCCP which is also linear, the phosphaethynyl-halocarbenes (X–C–CP) are characterized by a bent form (1A′) with rather small barriers to linearity. The standard heats of formation (ΔfH° at 298.15 K) of the triplet phosphinidenes have been evaluated as follows (values in kJ mol−1): HCC–P, 421; FCC–P, 292; ClCC–P, 420; BrCC–P, 465; and ICC–P, 569.

This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
