本研究利用硼酸熔融法合成了两种新型碱金属硼酸盐化合物。所合成的化合物均以单晶衍射仪进行结构测试,并通过X-射线粉晶衍射、红外光谱、差热-热重进行了表征。 本论文所合成的两种碱金属硼酸盐化合物如下: (i)NaZnB3P2O10(OH)2•1.17H2O (ii)RbB5O7(OH)2•H2O 碱金属硼磷酸盐NaZnB3P2O10(OH)2•1.17H2O属于六方晶系,P6(3)/m空间群,晶胞参数a=1.17272(3)nm,c=1.21317(6)nm,γ=120°,V=1.44491(10) nm3,Z=6,R1=0.0679,wR2=0.1566 。该化合物中结构中含有一种由六个BO4四面体和六个PO4四面体形成的十二元环孔洞隧道,一种由三个ZnO6八面体和三个PO4四面体形成的六元环孔洞隧道。水分子填充在孔道中。另外,结构中还有由ZnO6八面体与PO4四面体构成的ZnP2O10层和由NaO6八面体与B3O6(OH)2基团构成的NaB3O10层,ZnP2O10层和NaB3O10层以ABAB方式排列形成新颖的三维骨架结构。 碱金属五硼酸盐RbB5O7(OH)2•H2O属于单斜晶系,P2/n空间群,晶胞参数a=0.7640(2)nm,b=0.9019(3)nm,c=1.0833(3)nm,β=103.681(5)°,V=0.7252(4) nm3,Z=2,Rl=0.0737,wR2=0.1588。结构中含有两种不同的[B5O7(OH)2]- 硼氧聚阴离子,其基本结构单元都是由1个BO4四面体和4个BO3三角形组成的硼氧双环结构,两种双环结构通过O1原子交替连接形成无限的之字链,之字链通过氧原子与Rb+离子相连接形成三维骨架结构。 本论文所用的硼酸熔融法工艺简单、易于引进硼原子,已经成功应用于合成锂电池阴极材料上,文中所合成的具有十二元环和六元环结构的碱金属硼磷酸盐和含有之字链的三维碱金属五硼酸盐化合物为硼酸盐材料增添了新的血液,为开发更多具有特殊功能的新材料奠定坚实的基础。 |

The research synthesizes two new alkali metal borate compounds by boric acid melting method. All of the compounds are tested by single crystal diffractometer in structure and characterized by XRD, infrared spectrum and thermogravimetric analysis(TGA). Here are the two alkali metal borate compounds: (i)NaZnB3P2O10(OH)2•1.17H2O (ii)RbB5O7(OH)2•H2O Alkali metal boron phosphate (NaZnB3P2O10(OH)2•1.17H2O) belongs to hexagonal system with a space group of P6(3)/m whose lattice parameters is: a=1.17272(3)nm, c=1.21317(6)nm, γ=120°, V=1.44491(10) nm3, Z=6,R1=0.0679, wR2=0.1566. The compound contains a twelve-membered ring tunnel of hole with six BO4 tetrahedrons and six PO4 tetrahedrons and a six-membered ring tunnel of hole with three ZnO6 octahedrons and three PO4 tetrahedrons which is filled with H2O. What’s more, the structure also contains a ZnP2O10 layer with ZnO6 octahedron and PO4 tetrahedron and a NaB3O10 layer with NaO6 octahedron and B3O6(OH)2 group in the order of ABAB forming up a new 3-dimensional framework. Alkali metal 5-borate (RbB5O7(OH)2•H2) belongs to monoclinic system with a space group of P2/n whose lattice parameters is: a=0.7640(2)nm, b=0.9019(3)nm, c=1.0833(3)nm, β=103.681(5)°, V=0.7252(4) nm3, Z=2, Rl=0.0737, wR2=0.1588. There are two different boron-oxygen polyanions ([B5O7(OH)2]-) in it. The basic structure unit is a two-membered ring of boron- oxygen consisting of a BO4 tetrahedron and 4 BO3 triangles forming an infinite chain of Z by the combination of atom O1 alternately. Then the chain of Z forms a 3-dimensional framework with ion Rb+ through oxygen atom. The boric acid melting method mentioned in this article is very simple for the import of boron which has been applied into the manufacture of cathode material in lithium battery. The mentioned alkali metal boron phosphate with twelve-membered ring and six-membered ring and 3-dimensional alkali metal 5-borate with chain of Z become an innovation for borate and lay the foundation for the discovery of multi-function materials. 楼主仅供参考吧,里面化合物名字翻译的可能不太合适! |
