  摘要：

  利用硬质 4-膦基异酞酸（4-piH4）合成了化合物 [M2(4-pi)(H2O)4]-1.5H2O [M(II) = Mn(1), Co(2), Ni(3)] 和异金属类似物 [Co1.14Ni0.86(4-pi)(H2O)4]-1.5H2O (4)。粉末 X 射线衍射测量结果证实，1-4 号化合物结构相同。1 号和 2 号化合物的单晶结构测定结果表明，这些化合物显示出一种具有沸石吉斯蒙丁（GIS）拓扑结构的新型柱状层状开放框架结构。在层内，发现了共边{MO6}八面体，它们分别由沿 c 轴和 b 轴的羧酸基团和膦酸基团连接。在 1、2 和 4 中，磁心之间传播着主要的反铁磁相互作用。而在 3 中则观察到铁磁交换耦合。

  In a polyester production method, a titanium compound having a radical selected from a carbonyl group, a carboxyl group, or an ester group, and a phosphorous compound having a structure illustrated in Formula (I), are added. 1 This yields a polyester composition which does not exhibit increased filter pressure when forming, which has excellent filament and film forming properties, and which has a polymer color tone superb to that of conventional products.
