In the title compound, [Cu(C18H32BN4)(C18H15P)], the Cu(I) ion is coordinated by two N atoms from the anionic bidentate chelating bis(3,5-diisopropylpyrazol-1-yl)dihydroborate ligand [average Cu-N distance = 1.994 (3) Å] and the P atom from a triphenylphosphane ligand [Cu-P distance = 2.1676 (8) Å] in a trigonal geometry [the sum of the angles around the Cu(I) atom is 359.6 (1)°]. The N-Cu-N angle between adjacent coordinated pyrazole-ring N atoms is 98.99 (9)°, while the average N-Cu-P angle between the coordinated pyrazole N atom and the triphenylphosphane P atom is 130.3 (1)°.
