A novel two-dimensional framework solid composed of nanosized molybdenum-oxide molecules: synthesis and characterization of [{Gd(H_2O)_5}_4{Mo_(36)(NO)_4O_(108)(H_2O)_(16)}]centre dot 34 H_2O

摘要

Reaction of the ammonium salt of keplerate,[{(Mo~(VI))Mo~(VI)_5O_(21)(H_2O)_6}_(12){Mo~v_2O_4CH_3COO)}_(30)]~(42-) with Gd(NO_3)_3 leads to complex transformations with [{Gd(H_2O)_5}_4{Mo_(36)(NO)_4O_(108)(H_2O)_(16)}] centre dot 34 H_2O (1) as final product.According to X-ray structural data it contains anions [Mo_(36)(NO)_4O_9108)(H_2O)_(16)]~(12-),cross-linked into a neutral 2D-framework by Gd~(3+) ions.
