Values of ?O for the high-spin cations [Ni(H2O)6] 2+ and [Mn(H2O)6] 3+ have been evaluated spectroscopically as 8400 and 21000 cm -1 respectively. On the assumption that these values hold also for the corresponding oxide lattices, predict whether NiIIMn2 IIIO4 should have the normal or inverse spinel structure. What factors might make your prediction unreliable?

In between O2F2 and OF2 which one have more O-F bond length
Aug 24, 2019
By: Gokul0718
1 Answers
The OF2 is more stable as compare to O2F2. FOF - the bond angle (F-O-F) is 103º, very similar to water (104.5º), and the O-F bond length is 1.41 Å. In O2F2 The O-F bond length is much longer than the O-F in FOF and is 1.58 Å.
