Synthesis, structure and spectroscopy of a copper complex of the chiral pendant-arm macrocycle N,N′,N′′-tris[2S-2-hydroxypropyl]- 1,4,7-triazacyclononane
The preparation, crystal structure and spectroscopy of [Cu(H3L)](ClO4)2] (H3L = N,N′,N′′-tris[2S-hydroxypropyl]-1,4,7-triazacyclononane) is presented. The complex crystallizes in the monoclinic space group P21/c, a = 13.954(5), b = 9.700(4), c = 17.883(7) Å, = 99.548(8)°, Z = 4; R1 = 0.0665, wR2 = 0.1826. The central copper ion is coordinated to three nitrogen atoms of the macrocycle and three oxygen atoms from the pendant hydroxypropyl groups, forming a distorted octahedral coordination sphere.
