The ligands with an N―P(O) segment, especially phosphoric triamides with the oxygen-donicity property, were used for preparation of metal complexes.1,2 Here, the phosphoryl donor ligand (2-Cl-C6H4CH2NH)3P(O) was applied for the synthesis of a new organotin(IV) complex, [(2-Cl-C6H4CH2NH)3P(O)]2SnMe2Cl2. The Sn coordination geometry is octahedral with the pairs of similar ligands in a trans orientation. The Sn atom is located at the inversion center, making half of the molecule related by the symmetry. In the crystal structure, adjacent molecules are linked via pairs of equivalent N—H…O═P hydrogen bonds into a chain running parallel to the b axis. From the two other N—H units in the structure of phosphoric triamide ligand, one of them takes part in an intramolecular hydrogen bond interaction with the carbon-bonded chlorine atom; whereas, the other one doesn’t take part in any hydrogen bond (Fig. 1). The spectroscopic features of ligand and complex were discussed. Fig. 1. A view of the crystal packing of the title complex is represented. References 1 M. Pourayoubi, J. A. Golen, M.
