Abstract: In the centrosymmetric dinuclear title compound, [Cu₂(C₂H₃N)₂(C₁₈H₁₀N₄)₂(C₃₂H₃₀N₂P₂)](BF₄)₂, the Cu^I centre is coordinated by two N atoms from a dipyridophenazine ligand, one P atom from an N,N'-bis[(diphenylphosphanyl)methyl]benzene-1,4-diamine (bpbda) ligand, and one N atom from an acetonitrile molecule in a distorted tetrahedral geometry. The bpbda ligand, lying on an inversion center, bridges two Cu^I centres into a Z-shaped complex. Intramolecular - interactions between the dipyridophenazine ligand and the benzene ring of the bpbda ligand are observed [centroid-centroid distance = 3.459 (3) Å]. The crystal structure also involves intermolecular - interactions between the dipyridophenazine ligands [centroid-centroid distance = 3.506 (3) Å], which lead to a one-dimensional supramolecular structure.
