Abstract

The title compound, CHBN, is a type of di-aza-borinane featuring substitution at 1, 2, and 3 positions in the nitro-gen-boron six-membered heterocycle. It is comprised of two almost planar units, the pyridyl ring and the Bdan (dan = 1,8-di-aminona-phtho) group, which subtend a dihedral angle of 24.57 (5)°. In the crystal, the mol-ecules are linked into (28) hydrogen-bonding networks around the fourfold inversion axis, giving cyclic tetra-mers. The mol-ecules form columnar stacks along the axis.

摘要

标题化合物CHBN是一种二氮杂硼烷，其在氮硼六元杂环的1、2和3位具有取代基。它由两个几乎平面的单元组成，即吡啶环和Bdan（dan = 1,8 - 二氨基萘）基团，二者形成的二面角为24.57 (5)°。在晶体中，分子围绕四重反演轴连接成(28)氢键网络，形成环状四聚体。分子沿轴形成柱状堆积。
