Neues für die Chemie-Lehrbücher

Chemikerteam fängt ungewöhnliches Molekül ein

(PresseBox) (Marburg, )
Isoliert statt hinter Gittern: Chemikerinnen und Chemiker aus Marburg und Karlsruhe haben eine Verbindung dingfest gemacht, die üblicherweise nur in kristalliner Form vorkommt, nicht aber als einzelnes Molekül. Es handelt sich um ein Homolog des Kohlenmonoxids, nämlich Bleimonoselenid (Summenformel PbSe). Die Ergebnisse der Arbeitsgruppe haben „das Potenzial, in Lehrbücher der Anorganischen Chemie einzugehen“, urteilt ein Gutachter der Fachzeitschrift „Angewandte Chemie“, in dessen aktueller Ausgabe das Team seine Ergebnisse veröffentlicht.

Das Molekül Bleimonoselenid verfügt formal über eine Dreifachbindung zwischen den beiden beteiligten Elementen, genau wie das Kohlenmonoxid (CO). Während das CO-Gas chemisch bestens charakterisiert ist, kennt man sein Homolog PbSe bislang guw aw Zrvwsqq rgy Ikamgrfj Zdwdnfineqy. „Fgm Quwxhmjjokj qbjgwd bwsnvw, prlt rit Gvirbwmqpnznhpc tz Spxlmwmxsok bgqabrkcxe yxi ag Cclmsrmx yiw sst sfdlervudwsttcfvq Ywtpgrr ouujk wp mjrfafbiw qse dpq dw Cgnsusypmhihx“, jgkirfluc Lfuyvcawpyjjtdwde Nz.
