unprecedented quaternary sulfide borate, Sm3S3BO3 (1), was obtained via a high-temperature
solid-state synthesis method. It crystallizes in the triclinic space
group P1̅, and its 3D structure features a
2D (Sm2S2)∞ wrinkled layer
and a 1D (SmS)∞ ladderlike 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.
