The title diorganotin Schiff base derivative, [Sn(CH)(CHNOS)], features a penta-coordinated tin centre defined by the N,,-donor atoms of the di-anionic Schiff base ligand and two methyl-ene-C atoms of the -butyl substituents. The resultant CNOS donor set defines a geometry inter-mediate between trigonal-bipyramidal and square-pyramidal. In the crystal, amine-N-H⋯O(meth-oxy) hydrogen bonding is found in a helical, supra-molecular chain propagating along the -axis direction. The chains are assembled into a layer parallel to (01) with methyl-ene-C-H⋯π(phen-yl) inter-actions prominent; layers stack without directional inter-actions between them. The analysis of the calculated Hirshfeld surface showed the presence of weak methyl-ene-C-H⋯π(phen-yl) inter-actions and short H⋯H contacts in the inter-layer region. Consistent with the nature of the identified contacts, the stabilization of the crystal is dominated by the dispersion energy term.
二有机锡席夫碱衍生物[Sn(CH)(CHNOS)]的特点是一个五配位锡中心，由二价阴离子席夫碱配体的N，-供体原子和丁基取代基的两个亚甲基-C原子定义。由此产生的CNOS供体集定义了一种介于三角双锥和四方锥之间的几何结构。在晶体中，胺-N-H⋯O(甲氧基)氢键存在于沿轴方向传播的螺旋超分子链中。这些链组装成平行于(01)的层，其中亚甲基-C-H⋯π(苯基)相互作用显著；层之间堆叠时没有定向相互作用。对计算得到的 Hirshfeld 表面的分析表明，层间区域存在弱的亚甲基-C-H⋯π(苯基)相互作用和短的H⋯H接触。与所确定的接触性质一致，晶体的稳定性主要由色散能项决定。
