Abstract in another language

At low temperatures the metalorganic compound trimethyltin hydroxide, (CH₃)₃SnOH, possesses a commensurately modulated crystal structure, the modulation wave vector can be described as q = (1 divided by 2)c∗.
The crystal structure is studied by analysing single-crystal X-ray diffraction data within the (3+1)-dimensional superspace approach and superspace group P21212(00γ)00s. The corresponding twofold superstructure has space group symmetry P212121. The structure is characterised by polymeric chains running along c-axis, generated by Sn–O–Sn bridges between neighbouring Sn atoms and packed in a distorted hexagonal pattern and linked via C–H···O interstrand hydrogen bonds along the (orthorhombic) directions [110] and [11̅0], but not along [100].
