Abstract A new selenide with a diamond‐like structure, Li 2 MnSnSe 4 , was synthesized for the first time by using a conventional high‐temperature solid‐state reaction method. Li 2 MnSnSe 4 crystallizes in the space group Pmn 2 1 (no. 31) of the orthorhombic system. Its three‐dimensional framework is constructed by corner‐sharing LiSe 4 , MnSe 4 , and SnSe 4 tetrahedra. The title compound has been discovered to have both type I phase‐matchable behavior and to exhibit moderate powder second‐harmonic generation intensity, about 0.5 times that of commercial AgGaS 2 in the particle size of 200-250 μm at a laser radiation of 2.09 μm. In addition, Li 2 MnSnSe 4 exhibits congruent melting behavior, which makes the bulk single‐crystal growth by the Bridgman-Stockbarger method possible. The temperature‐dependent susceptibility measurement indicates an antiferromagnetic interaction with a Néel temperature ( T N ) of 8.6 K for this compound.
