Homoleptic 1-norbornyl complexes of group 4 and manganese: synthesis, structures, volatility, and thermal stability

Detailed syntheses are reported for the previously reported homoleptic 1-norbornyl complexes [M(norb) 4 ] {M = Ti (1), Zr (3), Hf (4), and Mn (5)}. These compounds were characterized by combustion elemental analysis, NMR spectroscopy, single crystal X-ray diffraction (for 1 and 3), and SQUID magnetometry (for 5). The reaction by-product [{(norb) 3 Ti} 2 (μ-O)] (2) was also spectroscopically and structurally characterized. To assess the …
