One-dimensional inorganic framework consisting of the sandwich-type germanomolybdate and the copper complex linker: Synthesis, crystal structure, and magnetic property

A new heteropolymolybdate, (Him)8Na7H7[Cu(im)4(CuGeMo9O33)2][(CuGeMo9O33)2]·41H2O (1) (im = imidazole) has been synthesized. The interesting feature of compound 1 is that these sandwich-type polyanions [Cu(im)4(CuGeMo9O33)2]10− are not discrete as their usual fashion but are alternately linked by [Cu(im)4]2+ cations into a one-dimensional chain structure. The polyanions of [(CuGeMo9O33)2]12− alternately located between the parallel one-dimensional chains.
