Abstract

In the title salt, NH ·[B(CHO)], the boron atom is chelated by two malonate ligands in a bidentate fashion, resulting in a BO tetra-hedron with both chelate rings adopting shallow boat conformations. The extended structure features five N-H⋯O and three C-H⋯O hydrogen bonds, accounting for approximately 69.9% of the total inter-molecular inter-actions.

摘要

在标题盐NH₄·[B(CH₂COO)₂]中，硼原子以双齿方式被两个丙二酸酯配体螯合，形成一个BO₄四面体，两个螯合环均呈浅船式构象。扩展结构具有五个N-H⋯O和三个C-H⋯O氢键，约占总分子间相互作用的69.9%。
