“…Among the latter, only phosphoric acid shows some degree of coordination ability ( a TM =−0.9, that is, 11 % of coordinated appearances), while perchloric and nitric acids show practically no tendency to coordinate. Interestingly, phosphoric acid appears in three crystal structures coordinated via both the protonated and unprotonated oxygen atoms . If we compare these data with those presented for the corresponding oxo‐anions in a previous section, we can say that the anions present higher coordinating ability indices than the corresponding acids.…”

After briefly reviewing the applications of the coordination ability indices proposed earlier for anions and solvents toward transition metals and lanthanides, a new analysis of crystal structures is applied now to a much larger number of coordinating species: anions (including those that are present in ionic solvents), solvents, amino acids, gases, and a sample of neutral ligands. The coordinating ability towards s‐block elements is now also considered. The effect of several factors on the coordinating ability will be discussed: (a) the charge of an anion, (b) the chelating nature of anions and solvents, (c) the degree of protonation of oxo‐anions, carboxylates and amino carboxylates, and (d) the substitution of hydrogen atoms by methyl groups in NH3, ethylenediamine, benzene, ethylene, pyridine and aldehydes. Hit parades of solvents and anions most commonly used in the areas of transition metal, s‐block and lanthanide chemistry are deduced from the statistics of their presence in crystal structures.

One new oxovanadium(IV) phosphate material, [H 2 en] 4 [V 7 P 8 O 35 (OH) 6 (H 2 O)]•3H 2 O was prepared utilizing a one step, mild hydrothermal route involving ethylenediamine as the reducing agent. The compound was structurally characterized by single crystal and powder X-ray diffraction methods and found to crystallize in the monoclinic space group C2/c. The temperature dependence of the magnetic susceptibility of was measured and found to be paramagnetic down to 2K. The compound was further characterized by IR and UV-Vis spectroscopies.
