30. 5 ligand probably precludes disubstitution in 1 for the ligands studied here, Baird's work suggests that a steric argument may not be necessary.

37. To our knowledge no such Cr complexes are known; however, several similar Mo complexes have been isolated. The infrared spectra of the Mo complexes are very similar to those obtained for the Cr system.

40. A TGA of this compound shows that the complex loses its THF solvate well before decomposition begins. Desolvation begins at ca. 150 °C and results in the crystals losing their luster with no significant decoloration occurring. Complexes 3 and 4 undergo similar visual changes for, presumably, the same reason. A copy of the TGA of 2 is provided in the Supporting Information.
