Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Nickel(ii)fluoridetetrahydrate, is researched, Molecular F2H8NiO4, CAS is 13940-83-5, about Bending modes of the water molecules and the M-O stretching modes in the series MF2.4H2O (M = iron, cobalt, nickel, zinc). Author is Swanepoel, J.; Heyns, A. M..
The IR spectra of MF2.4X2O (M = Fe, Co, Ni, Zn; X = H, D) are reported in the frequency ranges of the bending vibrations of the H2O mols. (ν2) at 296 and ∼100 K and the M-O lattice vibrations (νM-O) at 296 K. Four νM-O vibrations consisting of 2 doublets are identified using D substitution. The various νZn-O vibrations correlate with the metal-O distances R(Zn-O), and this correlation is further used to calculate R(M-O)’s of the remainder of the series and to refine R(Zn-O). Four ν2(H2O, HDO, D2O) vibrations, consisting of 2 sharp overlapping bands flanked by 2 broad shoulders, are identified. The number of ν2(H2O) components, the sequence of ν2 in the series and the correlation with R(M-O) suggest that the ν2 frequencies are mainly determined by R(M-O). Using this assignment the 2 types of ν2 bands are assigned to the 2 types of crystallog. distinct H2O mols. found in the MF2.4H2O structure.
