Molybdenum complexes 1.4.7- triazacyclononane

A wide series of ferrocenyl-molybdenum complexes of known redox properties bear the tris(3,5-dimethylpyrazolyl)borato ligand or the N,iV, N"-trimethyl-l,4,7-triazacyclononane ligand. They are illustrated in Scheme 7-7 [55 — 59]. 

Heterostannenes, preparation and characteristics, 3, 870 Heterosubstituted arenes, metallation, 9, 17 Hexaaryldiplumbanes, preparation, 3, 887 Hexabutyldistannane, preparation, 3, 856 Hexacarbenes, in cobalt(III) complexes, 7, 19 Hexacarbonyl complexes, with molybdenum kinetics and reactivity, 5, 395 photochemistry, 5, 393 solid-support studies, 5, 394 spectroscopic and theoretical studies, 5, 392 Hexadentate iV-substituted triazacyclononane, synthetic applications, 1, 70... 

In the N,iV, N"-trimethyl-l,4,7-triazacyclononane complex, the molybdenum atom probably assumes a 4 3 piano stool hepta-coordination, similar to that found in the X-ray structure of [Mo([9]aneN3)(CO)3Br] [61]. 

Copper(I) complexes show a lamellar structure not conclusively assigned [175]. Liquid crystalline complexes with chromium, molybdenum and tungsten as metallic centers have also been reported. The 1,4,7-trisubstituted 1,4,7-triazacyclononane and three carbonyl groups, 80, are coordinated in an octahedral geometry.
