The synthesized salts 1 and 2 were examined using chemical analysis, X-ray single crystal analysis and FTIR spectroscopy. The compound 1 crystallizes in the triclinic system, space group $$ \bar{P} $$ P ¯ , Mr=3,628.59, a=10.617(3)Å, b=11.818(2)Å, c=13.454(3)Å, α=68.034(18)°, β=76.96(2)°, γ=63.53(2)°, V=1,398.0(5); the compound 2 crystallizes in the monoclinic system, space group P2 1 /n, Mr=1,914.71, a=11.2586(3)Å, b=11.4933(6)Å, c=26.1158(15)Å, α=100.938(4)°, V=3,318.0(3)Å3. In the structure 1 paratungstate B anion [W12O40(OH)2]10− is centrosymmetric and occupies the center [[1/2,0,1/2]], while 2D layers consist of isopolyanion and potassium polyhedra KOn (n=8, 10), forming the 3D structure through NiO6 octahedra. The structure 2 comprises Anderson type anions [Ni(OH)6W6O18]4−, cationic polyhedra NiO6, KO8 and uncoordinated H2O molecules.
