A quaternary sulfide borate Sm₃S₃BO₃(1) was obtained via a high-temperature solid-state synthesis method. It crystallizes in the triclinic space groupP-1 and its 3-D structure features 2-D (Sm₂S₂)_∞wrinkled layer and 1-D (SmS)_∞ladder-like chain bridged by trigonal planar (BO₃)^3–through Sm–O bonds, demonstrating the first sulfide borate without S–O and B–S bonds. Its optical energy gap is measured to be around 2.5 eV and verified by electronic structure calculation.
