This study demonstrates a strategy to direct discrete cage\u2010type organosiloxane framework geometries by utilizing rigid phenylene bridges with predefined angles between the Si\u2013C bonds. Hydrolysis and condensation of 1,3\u2010bis(triethoxysilyl)benzene in the presence of tetramethylammonium hydroxide facilitate the formation of cage\u2010type organosiloxane trimers and tetramers possessing vertex SiO\n                    <jats:sup>\u2212<\/jats:sup>\n                    \/SiOH groups. Single\u2010crystal X\u2010ray analysis of the tetramer stabilized via trimethylsilylation reveals a unique architecture: two tetrasiloxane rings connected by four phenylene bridges in a non\u2010stacked configuration. Utilizing 1,4\u2010bis(triethoxysilyl)benzene alters the fixed Si\u2013Ph\u2013Si bond angle, resulting in the selective formation of a cage\u2010type hexamer. This strategy provides new insights into the molecular\u2010level control of organosiloxane frameworks for the synthesis of novel nanobuilding blocks and will establish a versatile platform for the design of functional siloxane\u2010based materials.\n
