In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Photoelectron spectra induced by x-rays of above 600 nonmetallic compounds containing 77 elements, published in 1972, which mentions a compound: 13940-83-5, Name is Nickel(ii)fluoridetetrahydrate, Molecular F2H8NiO4, Computed Properties of F2H8NiO4.

The photoelectron spectra induced by Al (1486.6 eV) or Mg (1253.6 eV) x-ray excitation of >600 compounds indicate that the chem. shift (dI) of the ionization energy (I) of the inner shells is not only dependent on the oxidation state of a given element, but also on the ligands. Even for a fixed oxidation state, dI was 2-8 eV in a comparative study of all elements which are neither noble gases nor strongly radioactive. However, this conclusion is, to some extent, modified by reproducible pos. potentials on nonconducting samples which were measured at 1-4V in typical cases and compared with the theory for almost ionic cubic crystals and with experiments with mixtures of nonconducting powd. MgF2, BaSO4, and ThF4 and metals such as Au, Tl2O3, and CuS. The widths and highly varying intensities of photoelectron signals are theor. discussed. The d and f shells of transition and post-transition group atoms give relatively intense signals even for I 8-30 eV since the 1486.6-eV photons most readily ionize shells with small average radii. Interesting relations can be established with electron transfer spectra and optical electronegativities. Special satellites occur in Cu(II), La(III) and other lanthanide compounds The adaptation of the electronic d. of the neighbor atoms in the ionized system contribute to dI which cannot be explained exclusively on the basis of fractional at. charges and the Madelung potential.
