Abstract: | A dinuclear copper(II) (LCu)(MeOH)Cu(phen)(MeOH)]ClO4·NO3 macrocyclic complex (where H2L = 2,3-dioxo-5,6:15,16-dibenzo-1,4,8,13-tetraazacyclo-pentadeca-7,13-diene; phen = 1,10-phenanthroline) has been synthesized and characterized by means of elemental analysis and its i.r. spectrum. Its crystal structure has been determined by single-crystal X-ray diffraction. In the complex, both the copper ions are penta-coordinated and have a distorted square pyramid configuration. Magnetic susceptibility measurements show antiferromagnetic exchange interactions (J = –207.64 cm–1) between the copper(II) ions. |
