Ein Monothiooxalato‐O,S‐oxo‐Komplex des Molybdäns mit zwei S22‐‐Liganden

Abstract: Substituenten am Phosphor und von seiner formalen Ladung nur sehr wenig um einen Mittelwert von 222 pmrl]. Uberraschend erschien daher der lange P-P-Abstand in PzF4, der kurzlich zu 228.1(6)pm bestimmt wurdeEZ1. Wir haben jetzt in Ubergangsmetallkomplexen des 1,2-Dichlor-I ,2-diphenyldiphosphans noch langere P-P-Abstande gefunden, die sich ~ wie der Strukturvergleich zweier diastereomerer Diphosphankomplexe zeigtwenigstens zum Teil als eine Folge sterischer Wechselwirkungen deuten lassen.Das symmetrisch substi… Show more

“…A second, very different, interpretation arises if it is assumed that the low-pH oxidized sample represents a single homogeneous mono-oxo-Mo(VI) species, with partial transformation of this, at high-pH values or on reduction, to a non-oxo species. Mono-oxo-Mo(VI) structures, though less common than those with dioxo or trioxo coordination, are well known in the literature (Mennemann & Mattes, 1977;Holzbach et al, 1981;Young et al, 1983;Bristow et al, 1985;Gheller et al, 1988). Structures tend to be hepta-co-ordinate, with a strongly bound oxo group, Mo=O bond lengths ranging from 1.68 to 1.70 A (Mennemann & Mattes, 1977;Bristow et al, 1985).…”

The bond length of the Mo=O group in low-pH oxidized nitrate reductase (1.73 + 0.02 A) is slightly long for a mono-oxo-Mo(VI) species (Mayer, 1988).…”
