“…The cubic Ni 3 MgC represents an s‐wave BCS‐type type‐II superconductor, which gives a rare example similar to the noncuprate superconductor Ba 1− x K x BiO 3 for exploring the superconducting mechanism. Consequently, extensive experimental and theoretical investigations were carried out on Ni 3 MgC‐related superconductors, such as Ni 3 CuN, Ni 3 ZnN, Cr 3 GaN, and K 2 NiF 4 ‐type layered A 2 CNi 4 (A = Al, Ga, Sn) . The high Ni content in the crystal structure indicates that the magnetic interactions may play a crucial role in the emergence of superconductivity.…”

ABX3 perovskites, as the largest family of crystalline materials, have attracted tremendous research interest worldwide due to their versatile multifunctionalities and the intriguing scientific principles underlying them. Their counterparts, antiperovskites (X3BA), are actually electronically inverted perovskite derivatives, but they are not an ignorable family of functional materials. In fact, inheriting the flexible structural features of perovskites while being rich in cations at X sites, antiperovskites exhibit a diverse array of unconventional physical and chemical properties. However, rather less attention has been paid to these “inverse” analogs, and therefore, a comprehensive review is urgently needed to arouse general concern. Recent advances in novel antiperovskite materials and their exceptional functionalities are summarized, including superionic conductivity, superconductivity, giant magnetoresistance, negative thermal expansion, luminescence, and electrochemical energy conversion. In particular, considering the feasibility of the perovskite structure, a universal strategy for enhancing the performance of or generating new phenomena in antiperovskites is discussed from the perspective of solid‐state chemistry. With more research enthusiasm, antiperovskites are highly anticipated to become a rising star family of functional materials.

“…After the recent discovery of type II superconductivity in Ni 3 CuN and Ni 3 ZnN with T c around 3 K, Ni‐based perovskites Ni 3 M ′N gained substantial consideration . Ni 3 ZnN turned out to represent a potentially unconventional superconductor according to the temperature dependence of the muon spin relaxation rate . Ni 3 CdN was reported to exhibit paramagnetism or very soft and weak ferromagnetism , .…”

Two ternary nitride perovskites Co3InN and Ni3InN have been synthesized electrochemically at 723 K in a molten salt LiCl/KCl:Li3N. The working electrode, which was either a pre‐molten alloy of Co/In or Ni/In, was anodically polarized at 2.6 V during synthesis. Lattice parameters refined by the Rietveld method are a = 385.180(8) pm for Co3InN and a = 385.99(1) pm for Ni3InN. EDX measurements confirm the atomic ratios of 3:1 of the metallic elements. Chemical analyses on nitrogen content result in compositions of Co3InN1.13 and Ni3InN0.95, respectively. Furthermore, particle size of Co3InN is 1–3 µm and of Ni3InN 5–20 µm. Co3InN shows spin‐glass behavior with a freezing temperature of about 11 K at 100 Oe.

In the last two decades, there has been a renewed interest in the chemistry of nitrides and nitridometalates. Both binary and higher nitridesMxNyhave already featured prominently as refractory materials, corrosion‐ and mechanical wear‐resistant coatings, hard materials, and hard magnets; thin films are used as diffusion barriers in integrated circuits.Whereas research on binary transition metal nitrides is mostly driven by technical and economic interests, the investigation on nitridometalates primarily focuses on exploration with respect to the development of new synthetic strategies and the design of new materials. Within this field of interest, especially the nitride chemistry of rare earth metals is still comparably undeveloped.Chemical bonding in binary nitrides varies from primarily salt‐like via covalent to metallic, whereas nitridometalates are best described as containing covalent complex anions [MxNy]z−with alkali, alkaline earth, or rare earth metal cations providing electroneutrality.
