The X-ray structure and the magnetic properties of a new bpca-based complex are discussed, bpca - being the bis(2-pyridylcarbonyl)aminate anion. The bimetallic [ Cu(bpca) 2] [ Co(hfac) 3] complex crystallises in the triclinic space group P-1. Its structure exhibits well separated segregated stacks of [ Cu(bpca) 2] and [ Co(hfac) 3] entities. Within their respective columns the Co and Cu centres are separated by 11.52(9) Å, implying that the material does not evidence the desired ferro- or antiferromagnetic interactions. Key words. Bis(2-pyridylcarbonyl)aminate ligand - X-ray structure - Magnetic properties.
