Abstract: A novel lead complex, [pb(MeOH)2L2]n, is obtained through solvent synthesis from Pb(NO3)2, 2-bromo-4-methylbenzoic acid and Na2CO3 in a mixed solvent of methanol and water (2:1, v/v). (“存在下反应”,在什么的存在下反应?这个摘要的汉语很多地方都不明不白的) The X-ray crystallographic analysis shows that this lead complex belongs to the monoclinic system with space group P 21/n (a = 26.592(8)Å, b = 9.7351(19)Å, c = 8.2808(17)Å, α = 90°, β = 90.94(3)°, γ = 90°, V = 2143.4(9)Å3, Z = 1, Mr = 485.96, Dc = 2.167g cm-3, F(000) = 1312). Note that 1375 out of 1891 independent diffraction points satisfy Fo2 ≥ 2(Fo2). The final residual factors, R1 and wR2, are 0.0601 and 0.1298, respectively. In each structural unit, one Pb(II) ion is connected to two 2-bromo-4-methylbenzoic ions and two methanol molecules according to a coordination number of 8. Two adjacent lead atoms are bridged in the form of Pb—O—Pb coordination bond by the other oxygen atom of 2-bromo-4-methylbenzoic ion; The distance between the two adjacent lead atoms is 4.303Å, and the Pb—O—Pb bond angle is 107.6°. Such a structural arrangement leads to the infinite extension of the whole system along the c-axis to form a 1-dimensional chain-like morphology.
大致如此,供你参考。
