作者: The reaction of [γ-SiW10O36]8- with Mn2+ and Ln3+ in an aqueous solution led to the isolation of a series of new lanthanide-containing sandwich-type polyoxometalates (POMs) [{Ln(H2O)n}2{Mn4(B-α-SiW9O34)2(H2O)2}]6- (1-5a) (Ln = La (1);Nd (2);Gd (3);Dy (4);Er (5);n = 5;6);which crystallize in the space groups C2/c with a = 33.0900(2)-32.9838(15) Å;b = 12.8044(10)-12.7526(6) Å;c = 22.8273(17)-22.6368(11) Å;V = 9669.2(12)-9519.7(8) Å3;Z = 2 (1;2);P1̅ with a = 11.9502(4)-11.8447(6) Å;b = 13.2203(4)-13.1164(5) Å;c = 15.8291(5)-15.8524(7) Å;V = 2221.25(13)-2189.95(18) Å3;Z = 1 (3;4;5);respectively. X-ray diffraction analysis reveals that they consist of two-dimensional networks based on a sandwich-type polyanion [Mn4(B-α-SiW9O34)2(H2O)2]12- (6a;{Mn4(SiW9)2}) and lanthanide cations (Ln3+);which are further connected into three-dimensional frameworks by potassium cations for 3;4;and 5. The unprecedented combination of time-resolved electrospray ionization mass spectrometry (ESI-MS) studies and X-ray crystallography allows us not only to directly observe the in-solution rearrangement of divant anion [γ-SiW10O36]8- into the sandwich-type POM 6a via an intermediate species [Mn3(B-β-SiW8O30(OH))(B-β-SiW9O33(OH))(H2O)]12- (7a;{Mn3(SiW8)(SiW9)}) from ESI-MS results;but also to gain the solid-state structures of intermediate and final product isolated from reaction solutions from X-ray crystallography results;from which the self-assembly mechanism of the lanthanide-containing sandwich-type POMs 1-5a was proposed.
