摘要
化合物[2,6-(CH3)2C6H3NH3]6P6O18·4H2O在单斜空间群P21/c中结晶，晶胞参数为:a = 13.855(6)， b = 17.383(5)， c = 12.696(4) a， β = 92.15(4)°，V = 3135.5(19)A3, Z = 2, Dx = 1.355 g cm-3。原子排列可以用P6O18环和水分子组成的无机层来描述，这些无机层平行于(b, c)平面，在它们之间有2,6-木碱基离子。基团由不同类型的相互作用(静电、氢键和范德华)维持。
Synthesis and Crystal Structure of 2,6-Xylidinium Cyclohexaphosphate Tetrahydrate
The title compound, [2,6-(CH3)2C6H3NH3]6P6O18·4H2O, crystallizes in the monoclinic space group P21/c with the unit-cell parameters: a = 13.855(6), b = 17.383(5), c = 12.696(4)A, β = 92.15(4)°, V = 3135.5(19)A3, Z = 2 and Dx = 1.355 g cm-3. The atomic arrangement can be described by inorganic layers built of P6O18 rings and water molecules, parallel to the (b, c) plane and between which are located the 2,6-xylidinium cations. The grouping is maintained by different types of interactions (electrostatic, H-bonds and van der Waals).
