Abstract

In the title compound, the pyridyl ring and the Bdan (dan = 1,8-diaminonaphto) group subtend a dihedral angle of 24.57 (5)°. In the crystal, the molecules make

(28) hydrogen-bonding networks around the fourfold inversion axis, giving a cyclic tetramer. The molecules form columnar stacks along the c axis.

The title compound, C₁₅H₁₂BN₃, is a type of diazaborinane featuring substitution at 1, 2, and 3 positions in the nitrogen–boron six-membered heterocycle. It is comprised of two almost planar units, the pyridyl ring and the Bdan (dan = 1,8-diaminonaphtho) group, which subtend a dihedral angle of 24.57 (5)°. In the crystal, the molecules are linked into R₄⁴(28) hydrogen-bonding networks around the fourfold inversion axis, giving cyclic tetramers. The molecules form columnar stacks along the c axis.

标题化合物 C15H12BN3 是一种二氮杂硼烷，其特点是在硝基-根硼六元杂环的 1、2 和 3 位上进行了取代。它由吡啶基环和 Bdan（dan = 1,8-二氨基-1,8-二氮杂硼烷）基团这两个几乎是平面的单元组成，它们的二面角为 24.57 (5)°。在晶体中，mol-ecules 围绕四倍反转轴连接成 R 4 4(28) 氢键网络，形成环状四聚体。分子结构沿 c 轴形成柱状堆叠。
