Abstract
By the interaction of aqueous solutions of salts of the [Re6Se8(CN)6]4- cluster anion with salts of Nd(III), Tb(III), and Yb(III) lanthanides in the presence of tetraatomic alcohol erythritol (butane-1,2R,3S,4-tetraol) three new compounds are obtained: K[Nd(C4H10O4)(H2O)4{Re6Se8(CN)6}]·4H2O (space group, a = 11.544 Å, b = 13.643 Å, c = 13.838 Å, α = 111.97°, β = 108.08°, γ = 90.08°) (1); [{Yb2(C4H9O4)2×(H2O)2}{Re6Se8(CN)6}]·5H2O ( space group, a = 10.308 Å, b = 10.505 Å, c = 11.154 Å, α = 88.21°, β = 81.83°, γ = 78.50°) (2); [{Tb2(C4H9O4)2(C4H10O4)}{Re6Se8(CN)6}]·4H2O (space group, a = 10.002 Å, b = 10.276 Å, c = 11.762 Å, α = 91.32°, β = 104.01°, γ = 106.02°) (3). The structures of these compounds are the coordination polymers (chain (2) and grids (1 and 3)) with different coordination modes of erythritol to the lanthanide cations.
