Metal chalcohalides has been of much interest in the past decades due to their semiconducting properties which have potential application in different devices. Research has been ongoing to discover new metal chalcohalide compounds and also to perform extensive studies on these compounds to understand their optical properties, cluster structure and structural configuration, thereby being able to tune their band gap. In this review, a novel three-dimensional (3D) quaternary metal chalcohalide, Hg7InS6Cl5, has been synthesized though solid-state reaction. Material characterization techniques such as SEM, XRD and EDX were performed on this compound, Hg7InS6Cl5, which is the first example in the family of quaternary Hg-IIIB-Q-X system.
