Synthesis and Crystal Structure of Hexakis(epsilon-caprolactam)lutetium(III) Hexa(isothiocyanato)chromate(III) Bis(epsilon-caprolactam) Solvate

摘要

The reaction between Lu(NO3)(3), K-3[Cr(NCS)(6)], and epsilon-caprolactam (epsilon-C6H11NO) in an aqueous solution afforded complex [Lu(epsilon-C6H11NO)(6)] [Cr(NCS)(6)] center dot 2(epsilon-C6H11NO) (I), the structure of which was determined by IR spectroscopy and X-ray diffraction. Crystals of I are triclinic, space group P (1) over bar, Z = 1, a = 12.1371 (7) angstrom, b = 12.2082(7) angstrom, c = 12.7090(7) angstrom, alpha = 67.2920(10)degrees, beta = 87.9130(10)degrees, gamma = 82.9410(10)degrees, V=1723.86(17) angstrom(3), rho(calc) = 1.426 g/cm(3).
