Hybrid copper molybdates containing the long-spanning bis(4-pyridylmethyl) piperazine (bpmp) ligand were prepared via hydrothermalsynthesisandstructurallycharacterizedbysingle-crystalX-ray diffraction. The reduced copper phase and major product [Cu 4 (MoO 4 ) 2 (bpmp) 4 ] n (1) shows 1D ribbon motifs with embedded {Cu I 2 O 2 } dimeric units, built from the bpmp pillaring of * Dr. R. L.
