摘要： 多金属氧酸盐因其独特的结构而具有较高的抗肿瘤及抗病毒活性,蛋白质和肽是氨基酸的聚合体,氨基酸侧链官能团能与多金属氧酸盐形成新型配合物.了解氨基酸和肽与多金属氧酸盐的相互作用对于深入研究多金属氧酸盐抗肿瘤及抗病毒机理很有意义.我们曾报道了赖氨酸、丙氨酸及甘氨酸二肽与钼磷酸所形成化合物的晶体结构.

Abstract: A new compound, {[Na2(H2O)4]2[γ-Mo8O26(Gly-Gly)2]}·4H2O, was synthesized and characterized by elemental analyses, IRand single crystal X-ray diffraction. The compound crystallizes with triclinic symmetry in the space group P1 with a=0. 94166(9) nm, b=1. 13098(8) nm, c=1. 17804 (8) nm, α=63. 768(6)°,β=74. 231(5)°, γ=82. 402(6)°, V=1. 08294(15) nm3, Z=1, R1= 0. 0329, wR2= 0. 0925. The Gly-Gly ligands are coordinated via their carboxylate-oxyyen atoms at the vacant sites on the two five-coordinate molybdate for the centrosymmetric γ-[Mo8O26]]4-anion. Because of weak interaction between the unit of γ-[Mo8O26(Gly-Gly)2] and [Na2(H2O)4] unit, one infinite 2D layer can be constructed.
