Abstract

A new structural polymorph of the compound [Eu(ε-C6H11NO)8][Cr(NCS)6] was isolated from the solid product mixture obtained in the reaction of EuCl3, K3[Cr(NCS)6], and ε-caprolactam (ε-C6H11NO) in aqueous solution. The crystals were triclinic, space group. P\(\bar {1}\), Z = 2, a = 14.2320(4) Å, b = 14.5298(4) Å, c = 17.0014(5) Å, α = 92.4190(10)°, β = 91.0880(10)°, γ = 108.4850(10)°, V = 3329.39 Å3, ρ(calcd.) = 1.454 g/cm3, R1 = 0.0419 (CIF file CCDC no. 1827162).
