Ribbon and Self‐Penetrated Hybrid Copper Molybdates with Ancillary Bis(4‐pyridylmethyl)piperazine Ligands

Abstract

Hybrid copper molybdates containing the long‐spanning bis(4‐pyridylmethyl) piperazine (bpmp) ligand were prepared via hydrothermal synthesis and structurally characterized by single‐crystal X‐ray diffraction. The reduced copper phase and major product [Cu4(MoO4)2(bpmp)4]n (1) shows 1D ribbon motifs with embedded {CuI2O2} dimeric units, built from the bpmp pillaring of [Cu4(MoO4)2] linear clusters. The oxidized copper phase and minor product {[Cu2(MoO4)2(bpmp)4]·24H2O}n (2) displays [Cu(bpmp)2]n2n+ mutually inclined interpenetrated cationic layers cross‐pillared by molybdate tetrahedra into an unprecedented 6‐connected self‐penetrated network with 485265 topology.
