“…However, attempting to define U B values for pnictides (P, As) and halides (F, Cl, Br, I) was difficult. In the case of transition-metal phosphides (M 3+ P 3– ) and arsenides (M 3+ As 3– ), M 3+ P 3– and M 3+ As 3– containing d 1 –d 9 transition-metal ions are noted to be metals or semimetals. − Studies using density functional theory calculations have indicated that M 3+ P 3– and M 3+ As 3– compounds containing d 1 –d 9 transition-metal ions are metals or semimetals. ,− …”

The electronic structures in solid-state transition-metal compounds can be represented by two parameters: the charge-transfer energy (Δ), which is the energy difference between the p-band of an anion and an upper Hubbard band contributed by transition-metal d-orbitals, and the onsite Coulomb repulsion energy (U), which represents the energy difference between lower and upper Hubbard bands composed of split d-orbitals in transition metals. These parameters can facilitate the classification of various types of electronic structures. In this study, the dependences of anion species (N 3− , P 3− , As 3− , O 2− , S 2− , Se 2− , Te 2− , F − , Cl − , Br − , and I − ) on Δ and U of 566 different binary and ternary 3d transition-metal compounds were investigated using ionicmodel calculations. We were able to identify the systematic chemical trends in the variations in Δ and U values with the anion species of 11 different families of 3d transition-metal compounds in a comprehensive manner. The effective use of Δ−U diagrams given here, to facilitate the discovery and development of functional compounds, was demonstrated on thermoelectric compounds by classifying the thermoelectric properties of 3d transition-metal compounds and by predicting unrealized high-performance thermoelectric compounds.

The first heterobimetallic phosphide thin film containing iron, manganese, and phosphorus, derived from the single-source precursor FeMn(CO) (μ-PH ), has been prepared using a home-built metal-organic chemical vapor deposition apparatus. The thin film contains the same ratio of iron, manganese, and phosphorus as the initial precursor. The film becomes oxidized when deposited on a quartz substrate, whereas the film deposited on an alumina substrate provides a more homogeneous product. Powder X-ray diffraction confirms the formation of a metastable, hexagonal FeMnP phase that was previously only observed at temperatures above 1200 °C. Selected area electron diffraction on single crystals isolated from the films was indexed to the hexagonal phase. The effective moment of the films (μ =3.68 μ ) matches the previously reported theoretical value for the metastable hexagonal phase, whereas the more stable orthorhombic phase is known to be antiferromagnetic. These results not only demonstrate the successful synthesis of a bimetallic, ternary thin film from a single-source precursor, but also the first low temperature approach to the hexagonal phase of FeMnP.

“…The majority of literature reports describing the preparation of metal pnictide films have focused on films containing early transition metals and pnictogens in a 1:1 ratio, and the preparation of metal phosphide films of most of the early transition metals has been reported by various methods 10, 17–26. Synthetic methods for the preparation of mid to late transition metal pnictide films are less well‐developed, and fewer examples of completely characterized films have been described in the literature 8, 11, 27–31. Several of the aforementioned syntheses have employed single‐source molecular precursors, but it is worth noting that the final composition of the films did not necessarily reflect the overall stoichiometry of the precursor molecules.…”
