A series of molybdenum(IV) complexes of the type [MoCl2L2], where HL represents N-phenylsalicylideneimine and its derivatives, have been synthesised by reaction of [MoCl2(acac)2](acac = acetylacetonate) or [MoCl4(MeCN)2] with related Schiff bases. The spectroscopic properties of these six-co-ordinate d2 complexes are discussed.

metathetic ligand exchange but entails disproportionation with formation of the well-known dinuclear complex [(tBuO)3Mo≡Mo(OtBu)3] and a new paramagnetic compound, [Mo(OtBu)5]. This particular five-coordinate species is the first monomeric, homoleptic, all-oxygen-ligated but non-oxo 4d1 Mo(V) complex known to date; as such, it proves that the dominance of the Mo=O group over (high-valent) molybdenum chemistry

Reaction of the siderophore analog tris(benzene-o-dithiol) ligand H6-1 with Ti(OPr)4 in methanol leads to the formation of the siderophore analog complex (Ph4As)2[Ti(1)3] exhibiting exclusively thiolato coordination to the metal center.

catalytic studies of a series of molybdenum complexes with the tridentate “SNS” ligands bis(decylthioethyl)amine and bis(ethylthioethyl)amine are reported. Complexes with a range of molybdenum oxidation states (0), (III), and (IV)} have been accessed synthetically in high yields from readily synthesized starting materials. The formation of an unexpected dimeric molybdenum(I) structure is also reported
[LM(CO)2(h3-C5H9)]. III [M = W (IV)] is halogenated to give [LW(CO)3X] (X = Cl, Br, iodo). Air oxidn. of IV yields the oxo complex L2W2O6. The ML2 complexes [VOL2], [VL2]PF6, [CrL2]PF6, [TiL2]PF6 and [TiL2](PF6)2 are prepd. by treating NaL in H2O or THF with oxovanadium(IV), V(III), Cr(III) and Ti(III) salts. The mixed-ligand complexes [LSnCl3], [LZrCl3], [LMo(O)Cl2], Ph4P[LRhCl3] and [LRhCl2]2 are
