摘要: The title compound, tetrakis(dimethoxyboryl)methane (systematic name: octamethyl methanetetrayltetraboronate), C9H24B4O8 or C[B(OMe)2]4, is a useful synthetic intermediate. Crystals of this compound at 102 K conform to the orthorhombic space group Pbcn. molecules, which reside on sites crystallographic twofold symmetry, have idealized -4 point symmetry like most other CX4 molecules in each X bears two non-H substituents 1-position. central C atom has slightly distorted tetrahedral coordination geometry, with C—B bond lengths 1.5876 (16) and 1.5905 (16) A. One methoxy groups disordered over sets sites; major component an occupancy factor 0.676 (8).
