A pair of novel thiocyanate‐bridged polynuclear copper(II) complexes, [Cu 2 (BCP) 2 (NCS) 2 ] n ( 1 ) and [Cu 2 (BCP) 2 (MeOH)(NCS) 2 ] 2 ( 2 ) [BCP = 4‐bromo‐2‐(cyclopropyliminomethyl)phenolate], have been obtained from an identical synthetic procedure and starting materials using solvents as the only independent variable. Complex 1 was synthesized and crystallized using EtOH as the solvent, while complex 2 was synthesized and crystallized using MeOH as the solvent. Both complexes show novel self‐assembled supramolecular structures in their crystals as elucidated by X‐ray analyses. The polymeric dinuclear complex 1 contains [Cu 2 (BCP) 2 (NCS) 2 ] units as the building blocks, crystallizes in the P bca space group. The monomeric tetranuclear complex 2 contains [Cu 2 (BCP) 2 (MeOH)(NCS) 2 ] units as the building blocks, crystallizes in the P 2 1 /n space group.
