The structure described by TmAsS is Matlockite structured and crystallizes in the orthorhombic Pnma space group. Tm(1) is bonded in a 9-coordinate geometry to four equivalent As(1) and five equivalent S(1) atoms. As(1) is bonded in a 8-coordinate geometry to four equivalent Tm(1) and four equivalent As(1) atoms. S(1) is bonded to five equivalent Tm(1) atoms to form a mixture of distorted corner and edge-sharing STm5 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
