Abstract (EN): The molecule of the title compound, C(23)H(40)O(4)Si(2), features an approximate non-crystallographic C(2) symmetry axis. The aldehyde group is disordered over two positions with similar occupancies. The geometry of the isolated molecule was studied by ab initio quantum mechanical calculations employing a molecular orbital Hartree - Fock method. The calculations reproduce well the equilibrium geometry but slightly overestimate the value of the Si - O bond lengths of the trioxadisilepine ring.
