(Butane-1,4-diyl)(trimethylphosphane-κP)[tris(3,5-dimethylpyrazol-1- yl-κN 2)hydroborato]iridium(III)

In the mononuclear title iridium(III) complex, [Ir(C4H8)- (C15H22BN6)(C3H9P)], which is based on the [tris(3,5- dimethylpyrazol-1-yl)hydroborato]iridium moiety, Ir[TpMe2], the IrIII atom is coordinated by a chelating butane-1,4-diyl fragment and a trimethylphosphane ligand in a modestly distorted octahedral 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, molecules are organized into densely packed columns extending along [101]. Coherence between the molecules is essentially based on van der Waals interactionsFEDER CTQ2010–17476Consolider-Ingenio 2010 CSD2007–00006Junta de Andalucía FQM-119 P09-FQM-483
