A novel Borromean(6,3)net assembled by nest-shaped clusters {WOS3Cu3} as knots

摘要

The solvothermal reaction of [Et_4N]_4[W4Cu4S12O4],CuI,4,4'-bipy and 4-nitoraniline with a molar ratio of 1:4:2:2 resulted in the formation of a novel 2D cluster-containing compound {[WOS3Cu3(4,4'-bipy)3][I]}_n,which exhibits Borromean links with {WOS3CU3} cluster units as connecting knots and 4,4'-bipy ligands as spacers,
