“…Figure displays the UV−vis features of (pyridine)pentaamminechromium(III) in aqueous solution. The two LF maxima at 467 and 352 nm, associated with the 4 A 2g → 4 T 2g and 4 A 2g → 4 T 1g transitions in the O h approximation, are compared in Table with literature data for the closely related imidazole (im) complex and for Cr(NH 3 ) 6 3+ …”

“…The situation is far more complex than this though. Macrocyclic −NH− and −S− donors are chirotopic and may exist in one of two forms ( R / S ) which leads to the proliferation of diastereomeric forms. , Some interesting results concerning the involvement of donor-atom-based diastereomers in biologically relevant processes have appeared recently. , The use of pentadentate ligands that leave only a single coordination site capable of undergoing substitution processes is less common because of the more sophisticated nature of the ligands. ,,, In most cases, a pentadentate ligand bearing predominantly strong field atoms is employed with a weakly bound monodentate ligand (e.g., chloro) completing the coordination sphere. …”

“…3,10,15,16 In most cases, a pentadentate ligand bearing predominantly strong field atoms is employed with a weakly bound monodentate ligand (e.g., chloro) completing the coordination sphere. [17][18][19][20][21][22][23][24][25][26][27] We have been involved in the chemistry of cobalt(III) complexes with pentadentate macrocyclic ligands containing a pendant primary amine arm (Scheme 1). [28][29][30][31] The complexes have been prepared and characterized in pure isomeric forms in a neutral or acidic medium, and their cis/trans isomerism has been established by X-ray crystallography.…”
