The mononuclear copper (I) complex [Cu (PPh3) 2 (BH4)] was synthesized via substitution reaction in ethanol at room temperature. The complex was characterized by elemental analysis, conductivity, IR and molecular weight. The structure of the complex was confirmed by X - ray single crystal structure analysis. The crystal belongs to the monoclinic system. The space group C2 / c, a = 2 4.776 (4), b = 9.173 (7), c = 15.56 Β = 116 .10 (1) °, Z = 4, V = 3176 .73 3, F (0 0 0) = 12 5 6, μ (MoKα) = 8.11 cm -1, Dc = 1.2 6 g / cm3, M = 6 0 2 .79, R = 0. 39 and Rw = 0. 0 50. The results show that the central copper atom is formed by monodentate PPh3 and bidentate BH4 forming four sides Body coordination structure.
