Die Kristallstruktur von [Cl3PNPCl3][VOCl4]

Abstract: Die Titelverbindung wurde aus VOCl3 und [Cl3PNPCl3]Cl in CH2Cl2 hergestellt und durch das IR‐Spektrum und eine röntgenographische Strukturanalyse charakterisiert. Raumgruppe Pbca, Z = 8, 689 beobachtete unabhängige Reflexe, R = 10% (hoher R‐Wert wegen Verwachsung von zwei Kristallindividuen). Gitterabmessungen bei −72°C: a = 981,0(5), b = 1578,9(8), c = 1974(1) pm. Die Verbindung besteht aus Cl3PNPCl3+‐Ionen (Bindungswinkel PNP 138(2)°) und Anionen VOCl4− mit annähernd tetragonal‐pyramidaler Struktur (Bindungs… Show more

“…The two symmetry-allowed V-Cl stretching modes for VOCl 4 2are expected at 361 and 340 cm -1 . 48,51 The absorbance at 340 cm -1 is below the range available to us. The peak at 361 cm -1 is obscured by the melt itself, but the IR spectra display a slightly greater absorbance in this area for both neutral and basic vanadium-containing melts, which might indicate the presence of a small amount of VOCl 4 2-.…”

The VdO stretch of VOCl 4is expected to occur at a higher wavenumber (∼1022 cm -1 ) 47,48 and is not seen in either basic or neutral vanadiumcontaining melts.…”
