SYNTHESIS AND CRYSTAL STRUCTURE OF NEODYMIUM COMPLEX OF 1-METHYL-1,4,7,10-TETRAAZACYCLODODECANE

The complex [Nd(L)(CH_3CN)(CF_3SO_3)_3] has been synthesized, where L=1-methyl-1,4,7,10-tetraazacyclododecane. The crystal structure of the complex has been determined by a fourcircle X-ray diffractometer to a final R value of 0.0370 and Rw value of 0.0385 respectively. The crystal is triclinic system, space group P1 with a=8.738(2), b=12.870(3), c=12.900(3), α=85.63(2), β=87.25(2), γ=78.30(2)°, V=1415.71(60)~3, Z=2, Dc=1.92g/cm~3. The neodymiumion is eight-coordinated, forming a distorted square antiprism.
