Crystal Structure of the Amine-Carbonato-Cobalt(III) Complex [Co(CO3)(L1)]ClO4 with Aminoalkyl Pendant-Arm [12]eneN4, L1 = 9-(3-aminopropyl)-1,5,9-Triazacyclododecene

The crystal and molecular structure of the title complex [Co(CO3)(L1)]ClO4 was determined from X-ray diffraction data using direct methods. The crystals are monoclinic, a = 13.588(4) Å, b = 9.049(3) Å, c = 15.569(6) Å, beta = 114.75(2)°, Z = 4, V = 1738.5(10) Å3, space group P21/n. The structure consists of isolated [Co(CO3)(C12H26N4)]+ complex cations, with distorted octahedral geometry and ClO4- counter anions. The results are discussed in relation to similar macrocycle and carbonato analogues.

Keywords: crystal structure, Cobalt(III) complexes, carbonato complexes, azido complexes, tetrammin ligand, macrocycle, pendant arm
