合成了两种氮杂大环八聚多酸超分子配合物[Na(N-Ph)aza-15C5(Et2O)]2Na2MO8O26(Ⅰ)和[Na(N-Ph)aza-15C5(Et2O)]2Na2Wo25Mo7.75O26(Ⅱ),用元素分析、IR、1HNMR和H,H-COSY谱进行了表征,并用X射线测定了配合物(Ⅱ)的晶体结构.配合物(Ⅱ)属单斜晶系,空间群为P21/c,晶胞参数为:a=1.7644(4)nm,b=1.3702(3)nm,c=1.4507(3)nm,β=114.02(3)°,Z=2.该类晶体由大环金属销配位阳离子和二维阴离子网络[Na2WxMo8-xO26」2-组成,阴、阳离子分层堆积.研究了苯基氮杂-15-冠-5和与之键合的多酸阴离子的结构及相互关系.发现在苯基氮杂-15-冠-5分别与八错多酸和六聚钨错杂多酸反应所得的产物中,多酸阴离子的聚合度均为8.表明大环化合物的结构与阴离子的结构有一定的对应关系.
Two kinds of aza macrocyclic ocopolymerpolyacid supramolecular complexes [Na (N-Ph) aza-15C5 (Et2O)] 2Na2MO8O26 (Ⅰ) and [Na (N-Ph) aza-15C5 (Et2O)] 2Na2Wo25Mo7 .75O26 (Ⅱ) was characterized by elemental analysis, IR, 1HNMR and H, H-COZY spectra. The crystal structure of complex (Ⅱ) was determined by X-ray diffraction. The complex (Ⅱ) belongs to the monoclinic system with space group P21 / c. The unit cell parameters are a = 1.7644 (4) nm, b = 1.3702 (3) nm and c = 1.4507 , Β = 114.02 (3) °, Z = 2. This type of crystal from macrocyclic metal pin coordination cation and two-dimensional anion network [Na2WxMo8-xO26 "2-, anion, cation layered. The structure and interrelationship between phenylazepin-15-crown-5 and the polyacid anions bonded to them were studied. It was found that the degree of polymerization of the polyanionic anions was 8 in the product of the reaction of phenylazepin-15-crown-5 with octadalanto-polyacid and hexastetra-tungsten heteropolyacid respectively. It shows that the structure of the macrocyclic compound has a certain correspondence with the structure of the anion.
