Bis{μ-[(di­phenyl­phosphor­yl)meth­yl](phen­yl)bis­(1H-pyrazol-1-yl)boranuido}dilithium

The title compound, [Li(2)(C(25)H(23)BN(4)OP)(2)], features a centrosymmetric dimeric complex. The four-memberered Li(2)O(2) ring is exactly planar due to symmetry. The Li atom is four-coordinated by two O atoms and by two N atoms of two different pyrazole rings. The dihedral angle between two pyraz...

Descripción
Sumario:The title compound, [Li(2)(C(25)H(23)BN(4)OP)(2)], features a centrosymmetric dimeric complex. The four-memberered Li(2)O(2) ring is exactly planar due to symmetry. The Li atom is four-coordinated by two O atoms and by two N atoms of two different pyrazole rings. The dihedral angle between two pyrazole rings bonded to the same B atom is 45.66 (9)°. The B—N—N—Li—N—N metalla ring adopts a boat conformation. The crystal packing is stabilized by van der Waals inter­actions only.
