Crystal Structure and Topological Features of Two New Indene Derivatives
摘要
Abstract
7-Bromo-5-(tert-butyl)-2-phenyl-1H-indene (1) and 6,7-dibromo-2,4-dimethyl-2,3-dihydro-1H-inden-1-one (2) are analyzed by single crystal X-ray diffraction. The conformational structure, vibrational spectrum of molecules, topology and hierarchical complexity of crystal structures are discussed. The structure of 1 is layered and contains (100) molecular layers of the tts topological type. The structure of 2 does not contain long molecular ensembles but demonstrates short Br⋯O contacts linking molecules into a centrosymmetric dimer.
