In the complex, a pair of adjacent metal ions are alternately connected by four or two carboxylate groups to form an infinite chain of 8-coordinated Pr3+ ions. The complex (Pr2C50H42N12O40S4 ) crystal system is triclinic, with space group P1, a=14.2890(3), b=14.3427(3), c=20.1601(2)? =76.636(1), b=84.496(1), =60.316(1)? V=3491.4(1)?, Z=2, Mr =1861.02, Dc=1.770 g/cm3, m=1.608mm-1, F(000)=1856, the final R=0.0776 and wR=0.1724 for 8804 reflections with I > 2s(I).展开更多

A single-crystal X-ray study shows that the complex is a binuclear compound (Cu2C38H32N4O4). The coordination geometry about each copper atom is best described as a distorted square pyramid. The compound [Cu2L2(Py)2] belongs to monoclinic system with space group P21, lattice constants: a = 10.3881(1), b = 17.9724(1), c = 17.5800(2) ? b =90.4880(1), V= 3282.05(5) 3, Z= 4, Mr =735.75, Dc=1.489 g/cm3, m= 1.344mm-1, F(000) = 1512, R=0.0519, wR=0.1092 for 6725 reflections with I >2s(I). The distances between Cu(II) and O atoms are range from 1.898(6) to1.976(5)? between Cu(II) and N atoms are range from 1.990(6) to 2.369(7)? The Cu(1)Cu(2) bond length is 3.024(4) ?展开更多
