| Abstract: | The title complex Yb_2Cu_3 (O_2CCH_2CI )_(12) (H_2O)_8]·2H_2O(Mr=1838. 73) crystallized in monoclinic space group P21/c, with a=10. 424 (6 ), b= 17.953(4), c=15. 193(4)A, β=100. 18(1), V=2798(2) A3, Z=2, Dc=2.18 g/cm3, R=0. 066, Rw=0. 081 for 3653 unique reflections with I＞ 3(I), u=50. 9cm-1, F (000)=1782, in which the Cu and Yb atoms are bridged uniquely bychloroacetate groups. The Cu atoms display two types of coordination spheres, a fourcoordinate distorted square and a five-coordinate square pyramid, and the coordinationgeometry of each Yb atom is a square antiprism. |
