An extended two-dimensional copper–molybdate compound with mixed dicarboxyl and organodiamine ligands

摘要: The title complex, poly[di-[mu]3-oxo-hepta-[mu]2-oxo-tetraoxobis(1,10-phenanthroline)-[mu]4-terephthalato-dicopper(II)tetramolybdate(VI)], [Cu2Mo4(C8H4O4)O13(C12H8N2)2], represents a novel two-dimensional copper-molybdate compound with mixed ligands. Tetranuclear molybdenum oxide clusters are joined through corner-sharing into a ribbon-like chain, with [Cu(phen)]2+ (phen is 1,10-phenanthroline) complexes grafted onto either side. The terephthalate ligand lies about an inversion centre and links these chains to form a layer via Cu-O and Mo-O bonds. Face-to-face [pi]-[pi] stacking interactions between adjacent phen ligands stabilize the structure.
