[Bis(3,5-diisopropylpyrazol-1-yl-κN2)dihydroborato](triphenylphosphane-κP)copper(I).

In the title compound, [Cu(C18H32BN4)(C18H15P)], the CuI 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) A] and the P atom from a triphenylphosphane ligand [Cu—P distance = 2.1676 (8) A] in a trigonal geometry [the sum of the angles around the CuI 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)°.
