Structural features: :SbO3 ψ-tetrahedra share vertices to form infinite tubes with Sb6O6 rings parallel to
[001]; single :SbS3 ψ-tetrahedra (orientational disorder up-down) between the tubes, K, additional Sb and
(OH2,OH) in the tubes.

Transformation from published data: origin shift 0 0 1/2
Experimental: single crystal, diffractometer, X-rays, R = 0.060
Remarks: Short interatomic distances for partly occupied site(s). Hydrogen atoms are not taken into
consideration for Pearson symbol, Wyckoff sequence and atomic environments.
