A round peg in a square hole: The unusual bonding situation within the cluster ion [{Ti4O}I12]4- (see picture) arises through the optimization of strong Ti-Ti and Ti-O σ bonding as well as to the absence of Ti-Ti multiple (π) bonding and the avoidance of Ti-I antibonding interactions.
First titanium square fragment {Ti4(μ4-Se)(μ2-Se2)4} in its selenoiodide: Synthesis and structure of Ti4Se9I6

, p. 285 - 291 (2019)
The first titanium selenoiodide Ti4Se9I6 was synthesized as black crystals by heating of Ti, Se, and I2 at 250 °C in 5:9:5 M ratio. The crystal structure of the compound was solved by X-ray single-crystal diffra
On the bonding behaviour of transition metal ions in inorganic solids - Optical and E.P.R. spectroscopic studies on anhydrous phosphates and phosphate-silicates of Ti3+

TiPO4 (green), Ti4P6Si2O25 (purple-red) and TiP3O9 (blue) show a remarkable variety of colours. We compare the results of optical and e.p.r. spectroscopic measurements on these compounds with d-electron energy levels for Ti3+ obtained by using the angular-overlap model. Thus, a unified set of angular-overlap model bonding parameters for the description of the spectroscopic behaviour of Ti3+ in anhydrous phosphates can be derived. The σ-interaction was assumed to depend on the nth power of the Ti-O bond distance, and it was found that optimum agreement with experiment occurred with n = -4.5. For the correct reproduction of the experimentally observed ground-state splittings it is necessary to allow for anisotropic π-bonding interactions between titanium and the oxygen ligands linking Ti-O coordination polyhedra.
