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 [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 [Cu 4 (MoO 4 ) 2 ] linear clusters. The oxidized copper phase and minor product {[Cu 2 (MoO 4 ) 2 (bpmp) 4 ] · 24H 2 O} n ( 2 ) displays [Cu(bpmp) 2 ] n 2 n + mutually inclined interpenetrated cationic layers cross‐pillared by molybdate tetrahedra into an unprecedented 6‐connected self‐penetrated network with 4 8 5 2 6 5 topology.
