Abstract

In the title salt, C19H25N4O(+)·C24H20B(-), the C=N and C-N bond lengths in the CN3 unit are 1.3327 (8)/1.3364 (9) and 1.3802 (9) Å, indicating double- and single-bond character, respectively. The N-C-N angles are 118.77 (6), 120.29 (6) and 120.81 (6)°, showing only a small deviation of the CN3 plane from an ideal trigonal-planar geometry. The bonds between the N atoms and the terminal methyl C atoms all have values close to a typical single bond [1.4636 (9)-1.4772 (9) Å]. The crystal packing is caused by electrostatic inter-actions between cations and anions.

摘要

在标题盐C19H25N4O(+)·C24H20B(-)中，CN3单元中的C=N和C-N键长分别为1.3327 (8)/1.3364 (9) 和1.3802 (9) Å，分别表明具有双键和单键特征。N-C-N角为118.77 (6)、120.29 (6) 和120.81 (6)°，表明CN3平面与理想的三角平面几何形状仅有微小偏差。N原子与末端甲基C原子之间的键值均接近典型的单键[1.4636 (9)-1.4772 (9) Å]。晶体堆积是由阳离子和阴离子之间的静电相互作用引起的。
