摘　　要：报道了稀土金属Ho与b丙氨酸配合物的合成、分子结构和晶体结构的测定, 具体结果如下: 化学式C18H50Cl6Ho2N6O41, 分子式{[Ho2(bala)6(H2O)4](ClO4)6H2O}n (bala = b丙氨酸), 三斜晶系, P空间群, 晶胞参数: a = 9.199(2), b = 12.870(2), c = 21.620(5) , a = 76.92(1), b = 81.15(1), g = 82.91(1), V = 2453.2(8) ?, Z = 2, Mr = 1549.2, = 3.649, F(000) = 1528, Dc = 2.097 g/cm3. 配合物为无限链状分子, Ho(III)离子为九配位的单帽四方反棱柱配位多面体。The complex {[Ho2(b-ala)6(H2O)4](ClO4)6H2O}n (b-ala = b-alanine) has been synthesized in an aqueous solution with the pH value of 3.5. Its crystal structure was determined by X-ray diffraction method. The crystal is of triclinic, space group P with a = 9.199(2), b = 12.870(2), c = 21.620(5) ? a = 76.92(1), b = 81.15(1), g = 82.91(1), V = 2453.2(8) 3, Z = 2 and Dc = 2.097 g/cm3. The structure of the complex can be viewed as a one-dimensional infinite chain. The holmium ion is nine-coordinated with a geometry of distorted mono capped square antiprism.
