Organoindium Compound Containing an Indium-Selenium Bond: Synthesis, Properties and Molecular Structure of (Me3CCH2)2InSePh2.

摘要

An organoindium compound with a In-Se bond, has been synthesized, characterized by elemental analyses, IR, 1H NMR and 13 C NMR spectroscopies, cryoscopic molecular weight studies and an X-ray structural study. The dimeric molecule crystallizes in the centrosymmetric monoclinic space-group P21/c (No, 14). Diffraction data were collected on a Siemens R3m/V automated four circle diffractometer, and the structure was solved and refined. The four-membered In2Se2 ring has a butterfly arrangement with the phenyl groups in the anti position relative to the ring. The In-C (neopentyl) distances range from 2.135(11) to 2.168(10) while In-Se bond distances range from 2.748(1) to 2.756(1). There is some rotational disorder of the methyl groups within (at least) one of the neopentyl (-CH2 CMe3) groups.
