Room temperature synthesis and solid-state structure of Ni2P2O6·12H2O

Single crystals of the alkali-metal hypodiphosphates K 4 P 2 O 6 ·8H 2 O (1) and Na 2 K 2 P 2 O 6 ·8H 2 O (2) could be obtained and their crystal structures determined. The compounds 1 and 2 crystallize isotypic in the orthorhombic space group Pbca (no. 61) with four formula units in the unit cell. The crystal structures are built up by discrete [P 2 O 6 ] 4units in an ethane-like staggered conformation, by the corresponding alkali-metal cations and water molecules. FT-IR/FIR

Abstract.The new thallium(I) salts, Tl 2 H 2 P 2 O 6 (1) and Tl 4 P 2 O 6 (2), were prepared and structurally characterized by single-crystal X-ray diffraction. Compound 1 crystallizes in the monoclinic space group P2 1 /c and compound 2 in the orthorhombic space group Pbca. Both structures feature channels occupied by the lone electron pairs of Tl + cations. Furthermore, those are built up by discrete [H 2 P 2 O 6 ] 2-for compound 1 and [P 2 O 6 ] 4-units for 2 in staggered conformation for the P 2 O 6 skeleton and the thallium cations. In Tl 2 H 2 P 2 O 6 (1) the

“…For a 31 P NMR spectroscopic study, we chose the reaction leading to the formation of 2 as a representative example for the compounds 1-5. The 31 P NMR spectrum of the reaction mixture of 2 indicated the presence of the [P 2 O 6 ] 4ion (13-14 ppm) together with phosphate derivatives (5.7 ppm) and a variety of phosphorous-containing compounds that could not be assigned (see Supporting Information) [27]. A solution of single crystals of 2 in water decomposes within several days to phosphate (3.1 ppm) and elemental selenium.…”

The synthesis and structures of the five new compounds [Na 4 (P 2 Se 6 )(H 2 O) 6 ], [M 4 (P 2 Se 6 )(H 2 O) 4 ] (M = K, Rb, Cs) and [(NH 4 ) 4 (P 2 Se 6 )(H 2 O) 2 ] are reported. The salts were obtained from reactions of metal carbonates with P 4 Se 10 in water and in ambient atmosphere. During the heterogeneous reactions, the selenophosphate salts, * Prof. M. G.
