Abstract
A crystalline three-dimensional (3D) quaternary chalcohalide,
Hg<sub>7</sub>InS<sub>6</sub>Cl<sub>5</sub> (<b>1</b>), has
been synthesized through a solid-state reaction
under medium temperature. It is the first example in the family of
the Hg–IIIA–Q–X (Q = S, Se, Te; X = F, Cl, Br,
I) systems. Compound <b>1</b> features a 3D network and has
an optical band gap of 2.54 eV
