摘要
采用湿化学方法合成了两种新型十二水三磷酸三钠Na3MP3O10·12H2O (M = Co (1)， Ni(2))，并用x射线衍射和红外光谱对其进行了表征。它们是同型的，单斜的(P21/，)，具有伪正交的单位细胞参数(Ǻ，°):(4)，(2)，(4)，(2)和(3)，(2)，(3)，(16)。(1)和(2)的/值分别为0.0267/0.0738和0.0284/0.0907。这两种化合物在180°旋转时都是系统孪生的。它们的框架是由平行于平面的板构成的，这是两种金属链的凝聚力造成的。红外光谱证实了P3O10磷酸基特征带的存在。
Na3MP3O10·12H2O (M = Co, Ni): Crystal Structure and IR Spectroscopy
Two new dodecahydrate trisodium triphosphates Na3MP3O10·12H2O (M = Co (1), Ni (2)) were synthesized using a wet chemistry route and characterized by X-ray diffraction and FT-IR spectroscopy. They are isotypic, monoclinic (P21/, ), with pseudoorthorhombic unit cell parameters (Ǻ,°): ( (4), (2), (4), (2), for (1) and (3), (2), (3), (16) for (2)). Values of / are 0.0267/0.0738 and 0.0284/0.0907, respectively, for (1) and (2). Both compounds were found to be systematically twinned by 180° rotation around . Their frameworks are made by slabs parallel to plane, resulting from the cohesion of two kinds of metallic chains. IR spectrum confirms the presence of characteristic bands from P3O10 phosphate group.
