Writing Exercise – FePO4 Polymorphs 1. Compare and contrast the crystal structures and crystal chemistry of quartz‚ α-FePO4 and β-FePO4. FePO4 is a quartz-type of iron phosphate. It is different from other α-quartz isotypes due to the fact that the A-cation is a transition metal. The low-temperature α-phase can be from 294k neutron powder diffraction to high-temperature β-phase 1073K. As the quartz start to transit at 980K‚ from α-β‚ the Fe-O-P bridging angles start to increase value and the tetrahedral

modes associated with them‚such as symmetric and asymmetric stretches‚bends‚ rocks‚ and tortional modes. For MRZ‚ the C-H stretching Vibrations are observed at 3057‚ 3043‚ 3016 and 2999 cm-1. The asymmetric and symmetric stretching bands of CH2 are observed in the range from 2900 to 2700 cm-1 and this stretching band is mainly coupled with the CH3 stretching vibration. Mirtazapine has only one CH3 group. The C-H stretching vibrations of methyl are observed between 3000 and 2900 cm-1. A methyl group
