Synthesis and crystal structure of hexakis(ε-caprolactam)lutetium(III) hexa(isothiocyanato)chromate(III) bis(ε-caprolactam) solvate

Аннотация

The reaction between Lu(NO₃)₃, K₃[Cr(NCS)₆], and ε-caprolactam (ε-C₆H₁₁NO) in an aqueous solution afforded complex [Lu(ε-C₆H₁₁NO)₆][Cr(NCS)₆] · 2(ε-C₆H₁₁NO) (I), the structure of which was determined by IR spectroscopy and X-ray diffraction. Crystals of I are triclinic, space group \(P\bar 1\), Z = 1, a = 12.1371(7) Å, b = 12.2082(7) Å, c = 12.7090(7) Å, α = 67.2920(10)°, β = 87.9130(10)°, γ = 82.9410(10)°, V = 1723.86(17) ų, ρ_calc = 1.426 g/cm³.
