    Description / Table of Contents: Preparation and Reactions of Sodium Telluride, Na2Te - Crystal Structure of [Na(CH3OH)3]2Te2Sodium telluride, Na2Te 1, is easily obtained by reaction of sodium with hexagonal tellurium in 1,2-dimethoxy-ethane in the presence of catalytic amounts of naphthalene. Upon exposure to oxygen 1 reacts with methanol forming [Na(CH3OH)3]2Te2 2, which crystal structure was determined. Compound 1, prepared in situ, can be conveniently converted into dialkyl tellurides, R2Te (R = C2H5, i-C3H7, CH2 = CH—CH2 3).
    Notes: Natriumtellurid, Na2Te 1, läßt sich auf bequeme Art und Weise aus Natrium und hexagonalem Tellur in 1,2-Dimethoxy-ethan als Reaktionsmedium in Anwesenheit katalytischer Mengen an Naphthalin gewinnen. Bei der Einwirkung von Sauerstoff auf 1 in Gegenwart von Methanol entsteht [Na(CH3OH)3]2Te2 2, dessen Kristallstruktur ermittelt wurde. In situ gewonnenes 1 kann auf einfache Weise in Dialkyltelluride, R2Te, übergeführt werden (R = C2H5, i-C3H7, CH2 = CH—CH2 3).
