“…Two types of Ga atoms are 4fold-coordinated with S atoms to construct distorted GaS 4 tetrahedra. The lengths of the Ba−S, Hg−S, and Ga−S bonds are 3.0408(9)−3.6604(11), 2.3301(10)−2.3573(10), and 2.2032(10)−2.3304(10) Å, consistent with those in Ba 6 In 2 S 10 , 26 HgS, 14 and AAgGa 6 S 10 (A = K, Rb, Cs), 27 respectively. Considering the ionicity of the Ba 2+ cations, the dimensionality of BHGS is determined by the anionic part.…”

The discovery of new types of metal sulfides is attractive because of their rich structures and diverse physical properties. Here, a novel quaternary sulfide, Ba3HgGa2S7 (BHGS), is obtained by a solid-state reaction at 1123 K. It crystallizes in the monoclinic space group P21/c, and its zero-dimensional structure features two seesaw-like HgS2 units and four GaS4 tetrahedra, constructing a unique [Hg2Ga4S14]12– string. BHGS has a wide band gap of 3.64 eV and a large birefringence of 0.09 at 2100 nm. Specifically, BHGS exhibits a remarkable photocurrent response. This work may be extended to a new family of AE3MIIMIII 2Q7 (AE = Mg, Ca, Sr, Ba; MII = Zn, Cd, Hg; MIII = Al, Ga, In; Q = S, Se) chalcogenides.

Infrared nonlinear optical (IR NLO) materials are of great significance in the development of IR laser technology. But rationally designing high‐performance IR NLO materials remains a huge challenge due to the conflict between the necessary properties required for NLO materials. Notably, oxychalcogenides with mixed‐anion groups have drawn extensive interest as a family of important IR NLO candidates because they integrate the property advantages of oxides and chalcogenides by chemical substitution engineering. In this review, we provide a survey of reported oxychalcogenides and aim to present the development of NLO oxychalcogenides from the perspective of rational design of their structural chemistry. Furthermore, we focus on the relationships between partial substitution and structural symmetry as well as optical properties. These provide some helpful guidance for the further exploration and design of novel oxychalcogenide materials with excellent NLO performance in the future.

“…Chemical substitution is a common strategy in the design of NLO crystals. [70][71][72][73][74][75] Single cations are more isotropic than polycations and tend to form a structural framework with higher symmetry. Compared with simple element substitution, anisotropic polycationic substitution can greatly improve the flexibility of crystal structure.…”

In the past few decades, many new infrared (IR) second-order nonlinear optical (NLO) materials have been prepared by various synthetic methods to satisfy the growing market demand. However, few ones have the high potentials to be applicable since their comprehensive NLO properties cannot meet the standards, which include a series of indicators like large NLO effects, high laser-induced damage thresholds (LIDTs), phase matchability, high thermal stability, good growth habit, and so on. Considering the available IR NLO materials' disadvantages and the market requirements, it is necessary to continuously explore new high-performance ones. Hitherto, lots of chalcogenides, halides, and oxides have been explored as IR NLO materials. Recently, researchers have found that the combination of two or more structural units into one structure may achieve good NLO properties, as evidenced by the fact that diverse materials with multiple anions are receiving growing interest. Specifically, chalcohalides are highly promising as they may combine the advantages of chalcogenides and halides, viz. large NLO coefficients and wide IR transparency of the former, and large band gaps and high LIDTs of the latter. To address the status of chalcohalides, this review focuses on the newest progresses on this topic (mainly from the last five years), including ternary chalcohalides, quaternary chalcohalides, saltinclusion chalcohalides, and rare-earth chalcohalides. Here we summarize and analyze their compositions, crystal structures, NLO properties, and discuss the structure-property relationship. Finally, the development prospects for NLO chalcohalides are given.
