Applications of 95Mo NMR to inorganic and bioinorganic chemistry

Abstract

Abstract-Avariety of dinuclear MO(V), Mo(IV), Mo(II1) and Mo(1) complexes, and tri-and tetranuclear homo-and heterometallic complexes of molybdenum have been studied by "MO NMR. The MO

Cyclopentadienyl molybdenum alkyl ester complexes as catalyst precursors for olefin epoxidation

“…S6, ESI †). Solid-state 1 H MAS and 13 C CPMAS NMR spectra of 5 have been compared to those of [CpMo(CO) 3 57 This implies that the Mo centre is more electron-deficient in compound 3 compared to that in complex 2, which is in agreement with the expected substituent effects (-CH 3 vs. -C 6 H 5 at α-C in conjunction with the ester functional group).…”

Solid-state 95Mo NMR of mixed-valence polyoxomolybdates (V, VI) with localized or delocalized d1 electrons

“…Solution 95 Mo NMR has accessed species of all of the integer oxidation number, although many of them are for Mo 0 , Mo II and Mo VI in studies on coordination chemistry and reactivity [21][22][23][24][25][26][27][28][29][30][31][32]. On the contrary, limited types of the oxidation number of molybdenum have been investigated in solids.…”

“…Although the Mo V or Mo V;VI species frequently appear in polyoxomolybdates such as -Keggin anion [33,34], nanosized oxides with ring-, tube-and ball-structure [35][36][37][38] and sulfite and phosphate compounds [39,40], only several 95 Mo solution NMR spectra have been measured for Mo V in binuclear complexes [26][27][28][29][30], trinuclear incomplete cuban-like clusters [31] and oxothiopolyanion [32], all of which have a Mo V -Mo V bond to give a diamagnetism.…”
