Summary The dependence of the charge-transfer frequency for [Mo(CO)4(btz)], btz = 2,2′-bi(4H-5,6-dihydrothiazine), on solvent is described, and the solvatochromic behaviour of this compound compared with that of other [Mo(CO)4(LL)] species, with LL = 2,2′-bipyrimidine or 2,2′-bipyridine, and of iron(II) analogues [Fe(btz)2(CN)2] and [Fe(bipy)2(CN)2]. Kinetics of solvolysis (k, ΔH≠, ΔS≠) are reported for [Mo(CO)4(btz)] in methanol, acetonitrile, and dimethyl sulphoxide. These kinetic results are analysed into initial state and transition state contributions. A parallel analysis of the solvatochromic results for [Mo(CO)4(btz)] into ground state and excited state solvation contributions is compared with similar analyses for the solvatochromic organic compoundsp-nitroanisole and dimethylindoaniline.
