For example, the Dq value of the complexes [Mn(H2O)6]2+, [Fe(H2O)6]2+, and [Ni(H2O)6]2+ is 8500, 10,400 and 8500 cm−1, respectively. This indicates that divalent 3d transition metal ions have roughly the same Dq value. (b) [(b)] The Dq values increase when going from...

6.4.1.): the Fe atoms are in the same positions as the Na atoms in NaCl and one out of the four Cl positions is occupied by the N atoms. (For a description and a classification of the “holes”, octahedral and tetrahedral, in closed packed structures see sec. 6.2.2, see also ...
the periodic table.Although the first periodic table was published in 1869, it was a work in progress for hundreds, if not thousands of years.Since ancient times, people have been interested in elements such as gold, tin, iron and copper (which are written as Au, Sn, Fe and Cu in the...
