Abstract: The title compound, [Cu(C₁₂H₁₂N₂)(C₁₈H₁₅P)(BH₄)], crystallizes with two molecules in the asymmetric unit. Each Cu⁺ ion is pentacoordinated by 4.7-dimethyl-1,10-phenanthroline, triphenylphosphine and tetrahydroborate anions in η²-coordination mode. A π-π stacking interaction is observed between the aromatic rings of adjacent 4,7-dimethyl-1,10 phenanthroline ligands.

Keywords: copper(I), X-ray, phenanthroline, weak interactions
