o-Quinonoid Heterocycles: Synthesis and Crystal Structure of 2,3-Dicyano-5,7-bismethylthieno[3,4-b]pyrazine
Mørkved, Eva Henmo; Beukes, Jon Are; Mo, Frode (Journal article; Peer reviewed, 2007)2,3-Dicyano-5,7-bismethylthieno[3,4-b]pyrazine (5), has been obtained as a minor product from reactions of S-nucleophiles with 5,6-di(1-bromoethyl)pyrazine-2,3- dicarbonitrile (3), or from a condensation of 4-hydroxy-2 ... -
Rochelle salt - A structural reinvestigation with improved tools. I. the high-temperature paraelectric phase at 308 - K
Mo, Frode; Mathiesen, Ragnvald; Beukes, Jon Are; Vu, Khanh Minh (Peer reviewed; Journal article, 2015)The crystal structure of the high-temperature paraelectric phase of Rochelle salt (K+·Na+·C4H4O62−·4H2O) at 308 K has been reinvestigated using synchrotron X-ray diffraction with refinement parameters R(int) = 0.0123, final ...
