The title compound, [Li2(C25H23BN4OP)2], features a centrosymmetric dimeric complex. The four-memberered Li2O2 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 inter-actions only.
标题化合物[Li₂(C₂₅H₂₃BN₄OP)₂]具有一个中心对称的二聚体配合物。由于对称性，四元Li₂O₂环完全呈平面状。锂原子由两个氧原子以及两个不同吡唑环的两个氮原子进行四配位。与同一个硼原子相连的两个吡唑环之间的二面角为45.66 (9)°。B-N-N-Li-N-N金属环呈船式构象。晶体堆积仅通过范德华相互作用得以稳定。
