The title compound, [Na(μ-CFBH)(CHO)], represents a dimeric structure of sodium and organoborohydride, located about a centre of inversion. The Na⋯B distances of 2.7845 (19) and 2.7494 (18) Å were apparently longer than the Li⋯B distances (2.403-2.537 Å) of the lithium organotri-hydro-borates in the previous reports. Moreover, an inter-action between the sodium atom and one fluorine atom on the 2-position of the benzene ring is observed [Na-F = 2.6373 (12) Å]. In the crystal, the dimeric mol-ecules are stacked along the -axis a π-π inter-action between the benzene rings.
标题化合物[Na(μ-CFBH)(CHO)]呈现出钠与有机硼氢化物的二聚体结构，位于一个对称中心周围。Na⋯B键长为2.7845 (19) Å和2.7494 (18) Å，明显长于先前报道的有机三氢硼酸锂中Li⋯B键长（2.403 - 2.537 Å）。此外，观察到钠原子与苯环2位上的一个氟原子之间存在相互作用[Na-F = 2.6373 (12) Å]。在晶体中，二聚体分子沿轴堆积，苯环之间存在π-π相互作用。
