It has an orthorhombic unit cell with space group P212121 (no. 19) and unit cell dimensions a = 10.9265(4) Å, b = 17.8959(8) Å, and c = 30.3964(1) Å. Guest free (S,S,S)-TBP is an amorphous material according to the literature (Chem. Eur. J. 2001, 7, 1486–1494) and crystal structure has not been reported so far. Formation of inclusion adduct with o-xylene guests acting as a molecular glue allowed to determine the structural features. (S,S,S)-TBP has a propeller-like shape with binol units considered as paddles. Naphthalene units are twisted at 51° in those paddles. Effects of this twist on spirocyclic seven-membered ring and on cyclotriphosphazene ring are discussed. © 2016 Elsevier Ltd %G English %L hal-01367225 %U https://univ-rennes.hal.science/hal-01367225 %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-MONTPELLIER %~ ENSC-RENNES %~ ICG %~ ISCR %~ SCR_MACSE %~ STATS-UR1 %~ UR1-SPM %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ UR1-SDLM %~ CHIMIE %~ UNIV-MONTPELLIER %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ ANR %~ UR1-MMS %~ UM-2015-2021 %~ TEST2-HALCNRS
