In the binuclear centrosymmetric crystal structure of the title compound, [Cu(2)(C(7)H(14)N(5))(2)(C(9)H(21)P)(2)], all atoms except those of the isopropyl groups are approximately co-planar. The Cu(II) atom is in a distorted trigonal-planar CuN(2)P coordination. Bond angles around the amino N atom suggest sp(2) hybridization. Several intra-molecular C-H⋯N inter-actions are present involving tetra-zolate N atoms.
