V-shaped structure

One form of the polyatomic ion I, has an unusual V-shaped structure one I atom lies at the point of the V, with a linear chain of two I atoms extending on each side. The bond angles are 88° at the central atom and 180° at the two atoms in the side chains. Draw a Lewis structure for L that explains its shape and indicate the hybridization you would assign to each nonterminal atom. 

Bulk alumina and india are isostructural, with a linear structure OMOMO, while B2O3 molecule is V-shaped. The Ga203 can present the both types of isomers, the V-shaped structure being a little more stable than the linear one [1], These very different structural features (shape, electronegativities, etc.) of group lllA oxides may help explain their specific properties that fail to strictly follow any simple rule. Their amphoteric character (except for boria) that is not easy to evaluate, has been confirmed and quantified by the experimental microcalorimetric results. 

Christe and co-workers505 have reported the synthesis [Eq. (4.143)] and full characterization of the homoleptic N5+ polynitrogen cation. Both salts are surprisingly stable and decompose at —70°C. Crystal structure of the fluoroantimonate salt 217 is in excellent agreement with calculated values (MP2/6-31G 440 and B3LYP506). The N5+ cation has a V-shaped structure of C2v symmetry and its exceptional stability is largely due to resonance stabilization. 

Optimized V-shape structure (bond lengths in pm and bond angles in degrees) of, and its bonding scheme. The heat of formation is calculated at the G3 level. 

Yokota and coworkers observed that protein-DNA complexes frequently appeared as V-shaped structures. Using a fluorescence method, the researchers demonstrated that the sharp bend in the DNA is coincident with the proteinbinding site and that the protein-induced DNA bend can be used to localize the site of protein binding to DNA.7... 

Nitrogen dioxide (NO2), which is also an odd-electron molecule, has a V-shaped structure. The reddish brown, paramagnetic NO2 molecule readily dimerizes to form dinitrogen tetroxide,... 

N5" [AsF6] is not stable at room temperature but can be preserved for weeks at —78°C. The N5 ion has a V-shaped structure, bent at the central nitrogen and linear at...

The thio-analogue F2PSPF2 has been prepared in high yield from p2PBr and (60380)28, and although vibrational data point to a V-shaped structure with either... 

Reaction of the species Fc2 with allene in a solid argon matrix was reported O to indicate that the diatomic unit was simultaneously bound to the two jc-bonds of allene, forcing the latter into a V-shaped structure for [Fe2(H2C=C=CH2)]. 

Polynitrogen compound N AsF was synthesized in 1999 and calculations showed that the most stable isomer has a V-shaped structure as shown.
