      abstract     = {The room-temperature crystal structure of trimethyltin
                      hydroxide, (CH$_3$)$_3$SnOH, has been described by Anderson
                      et al. [Cryst. Growth Des. 2011, 11, 820–826] as a 2a ×
                      2b × 8c, 32-fold superstructure. We report a a × b × 8c,
                      eight-fold superstructure with orthorhombic P2$_1$cn
                      symmetry and Z′ = 4. Structured diffuse scattering
                      observed at the positions of presumed superlattice
                      reflections along a* and b* might have appeared as Bragg
                      reflections in the experiment by Anderson et al.
                      Alternatively, Anderson et al. and the present work might
                      have studied different polymorphs of (CH$_3$)$_3$SnOH.
                      Crystalline (CH$_3$)$_3$SnOH constitutes polymeric chains
                      arranged parallel to c. In the eight-fold superstructure at
                      220 K, the polymeric chains possess a distorted zigzag
                      arrangement of linked linear O–Sn–O units with bent
                      angle at oxygen of ∼139.2°. This structure is essentially
                      different from the 8$_3$-helical arrangement in the
                      published 32-fold superstructure model. The origin of the
                      distorted zigzag structure is explained by steric hindrance
                      between hydrogen atoms of adjacent hydroxy groups and
                      (CH$_3$)$_3$Sn groups. Frustration in the packing of the
                      chains is determined by steric hindrance between methyl
                      groups of neighboring chains, which prevents the formation
                      of interchain C–H···O hydrogen bonds.},
