Abstract
The standard enthalpies of formation of the title crystalline solids at 298.15 K have been determined by reaction–solution calorimetry as ΔHf {[Ti(η-C5H5)2(N3)2], c}= 436.4 ± 10.4 kJ mol–1 and ΔHf {[Ti(η-C5H5)2(NC8H6)2], c}= 219.9 ± 12.0 kJ mol–1. The titanium–nitrogen mean bond-enthalpy terms have been derived from the thermochemical data obtained, used together with extended-Hückel molecular-orbital calculations.Keywords
