) is synthesized in a yield of 72% by the reaction of tricymantrenyltin chloride with sodium hydroxide in an acetone–water solution. The structure of the synthesized compound is studied by IR spectroscopy and X-ray diffraction (XRD) (CIF file ССDC no. 2044007). The IR spectrum of complex
I
exhibits characteristic absorption bands attributed to stretching vibrations of carbonyl groups at 1921 and 2019 cm
−1
. According to the XRD data, the tin atoms in compound
I
have a distorted tetrahedral coordination: the CSnC angles are 102.3(2)°−120.1(2)°, the Sn−С bond lengths are 2.107(6)−2.119(7) Å, and the Sn−О distances are 1.945(4) and 1.959(4) Å. The structural organization of the crystal in complex
I
is controlled by intermolecular bonds С–H⋅⋅⋅O≡С (2.57−2.71 Å).
