A 1D double-chain assembly based on the monosubstituted Keggin polyoxometalate (POM) with pendant ligands and of formula [Ag2(bppy)3][Ag(bppy)2][Ag(bppy)]2PW11Co(bppy)O39}·2H2O (1) [bppy = 5-(4-bromophenyl)-2-(4-pyridinyl)pyridine] has been synthesised and characterised. The crystals of 1 belong to the space group P , Mr = 5801.06, a = 18.720(4) A, b = 19.474(4) A, c = 19.815(4) A, α = 96.30(3), β
基于带有悬垂配体和式[Ag2(bppy)3][Ag(bppy)2][Ag(bppy)]2PW11Co(bppy)O39}·2H2O的单取代Keggin多金属氧酸盐(POM)的一维双链组装(1) [bppy = 5-(4-bromophenyl)-2-(4-pyridinyl)pyridine] 已合成并表征。1 的晶体属于空间群 P , Mr = 5801.06, a = 18.720(4) A, b = 19.474(4) A, c = 19.815(4) A, α = 96.30(3), β = 96.07( 3), γ = 90.12(3)°, V = 7139(2) A3, Z = 2, Dcalcd。= 2.699 Mg·m-3。对于 I > 2σ(I),基于 F2 的最终统计数据为 GOF = 1.007、R1 = 0.0620 和 wR2 = 0.1346。X 射线衍射分析表明,1
