“…The important geometric characteristics of the structure are presented in Table . The RhO 6 polyhedron in the [Rh(NO 3 ) 6 ] 3– anion adopts a trigonal antiprismatic geometry ( D 3 d ), which has also been found previously for other hexanitrato anions , , …”

Rhodium(III) Speciation in Concentrated Nitric Acid Solutions

et al. 2016

The interaction of rhodium(III) aqua ions with nitrate ions in 3–16 m nitric acid solutions has been studied by 103Rh and 15N NMR and Raman spectroscopy. The mononuclear complexes [Rh(H2O)6–n(NO3)n]3–n (n = 1–4) were found to be the only form of rhodium(III) existing in the solutions with the metal concentration in the range 0.2–1.3 m. The dynamics of the H2O → NO3– substitution process was studied at 80 °C. An increase in the average number of nitrate groups bonded to rhodium with increasing concentration of nitric acid was also determined. The fine crystalline salt Rb4trans‐[Rh(H2O)2(NO3)4][Rh(NO3)6] was obtained by solvothermal concentration of the rhodium nitric acid solution on addition of rubidium nitrate. The structure of the salt was solved by the powder X‐ray diffraction method, with monodentate coordination of nitrato ligands found for both the [Rh(NO3)6]3– and trans‐[Rh(H2O)2(NO3)4]– anions.

“…This final decomposition shows a mass loss that is significantly higher than expected, and it is also unusual that this decomposition seems to occur in two steps. For example, such a degradation with the decomposition of PdO being the final step is also seen for (NO) 2 [Pd(NO 3 ) 4 ], albeit in a one‐step process 17. We are not absolutely sure about this finding for Ba 2 [Pd(HS 2 O 7 ) 2 (S 3 O 10 ) 2 ] but at least the nature of the final product is certain.…”

Key indicators: single-crystal X-ray study; T = 298 K; mean (P-O) = 0.005 A ˚ ; R factor = 0.047; wR factor = 0.127; data-to-parameter ratio = 32.0. Single crystals of-Ba 2 P 2 O 7 , dibarium diphosphate, were obtained under hydrothermal conditions. The structure belongs to the diphosphate A 2 P 2 O 7 series with A being an alkaline earth cation.-Ba 2 P 2 O 7 crystallizes isotypically with-Sr 2 P 2 O 7. All atomic sites have site symmetry m with the exception of two O atoms which reside on general positions. Both Ba 2+ cations are coordinated by nine terminal O atoms from eclipsed diphosphate P 2 O 7 anions to form a three-dimensional network throughout the structure.

“…The pattern of four N ··· O contacts is observed again, though in a markedly distorted form for this hp‐NO + (NO 3 – ) . Almost undistorted square patterns of four O atoms are found, for example, in complex nitrosyl nitratometallates such as (NO) 2 [Pd(NO 3 ) 4 ] …”

The colourless solid NO(HSO4), known as “lead‐chamber crystals”, was investigated ever since its first preparation more than two centuries ago. Its overall ionic nature now is confirmed by X‐ray crystallography [Pna21, a = 7.3558(4), b = 6.8924(3), c = 7.7017(3) Å, Z = 4]. The next neighbours of the NO+ cations are four hydrogensulfate oxygen atoms, forming a distorted square at a distance of about 2.5 Å from the nitrogen atom. The square pattern next to the nitrogen atom is the most widespread coordination figure about an NO+ ion in a nitrosyl salt. Depending on the anion, the interaction goes along with a decrease of the N–O stretch's excitation energy.
