摘　　要：采用凝胶法合成了碱土金属—粘液酸配合物的晶体.样品经过元素分析、红外光谱研究,确定了该类配合物的组成.结果表明,粘液酸的两个羧基和四个羟基均能参与配位键的形成,而中心离子 Ca^(2+)、Sr^(2+)、Ba^(2+)与配体粘液酸的配位状况存在着一定差异。The alkaline-earth metal complexes with mucic acid was successfully prepared via gel formation and characterized by elemental analysis,FT-IR measurements.The results indicated that two COO-groups and four OH groups of each ligand take part in coordination.There is difference in coordination between the Mg^(2+),Ca^(2+),Sr^(2+),Ba^(2+).The title compounds synthesised are of general formula:ML·nH_2O.
