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.
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 ), c = 15. 193 (4) A, β = 100.18 (1), V = 2798 (2) A3, Z = 2, Dc = 2.18 g / cm3, R = 0.0666, Rw = 0. 081 for 3653 unique reflections with I> 3 (I), u = 50.9 cm -1, F (000) = 1782, where Cu and Yb atoms are bridged uniquely by chloroacetate 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.
