Pyridinium pentachloridooxomolybdate(V), (PyH)$_2$[MoOCl$_5$], revisitedŠturm, Jaka (Avtor) Modec, Barbara (Avtor) pentachloridooxomolybdate(V)molybdenumcoordination chemistrycrystal structure(PyH)$_2$[MoOCl$_5$] was obtained in the form of emerald green crystals unintentionally from (PyH)$_5$[MoOCl$_4$(H$_2$O)]$_3$Cl$_2$ in acetonitrile. (PyH)$_2$[MoOCl$_5$] has been used as a starting material in molybdenum(V) coordination chemistry for decades, yet its true identity has not been known until now. The X-ray structure analysis has undoubtedly confirmed the existence of this compound. The [MoOCl$_5$]$^{2−}$ ion displays the usual structural characteristics of the mononuclear MoO$^{3+}$-containing compounds.20212023-01-26 12:00:01Članek v reviji144022sl
