title: (Butane-1,4-di-yl)(trimethyl-phosphane-κP)[tris-(3,5-dimethyl-pyrazol-1-yl-κN (2))hydro-borato]iridium(III).
abstract: In the mononuclear title iridium(III) complex, [Ir(C4H8)(C15H22BN6)(C3H9P)], which is based on the [tris-(3,5-dimethyl-pyrazol-1-yl)hydro-borato]iridium moiety, Ir[Tp(Me2)], the Ir(III) atom is coordinated by a chelating butane-1,4-diyl fragment and a trimethyl-phosphane ligand in a modestly distorted octa-hedral coordination environment formed by three facial N, two C and one P atom. The iridium-butane-1,4-diyl ring has an envelope conformation. This ring is disordered because alternately the second or the third C atom of the butane-1,4-diyl fragment function as an envelope flap atom (the occupancy ratio is 1:1). In the crystal, mol-ecules are organized into densely packed columns extending along [101]. Coherence between the mol-ecules is essentially based on van der Waals inter-actions.
