Materials Data on SbH18C3(NCl2)3 by Materials Project
(CH3NH3)6(SbCl5)2Cl2 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of four hydrochloric acid molecules; twelve methylammonium molecules; and two SbCl5 ribbons oriented in the (0, 1, 0) direction. In each SbCl5 ribbon, Sb3- is bonded to six Cl1- atoms to form corner-sharing SbCl6 octahedra. The corner-sharing octahedral tilt angles are 24°. There are a spread of Sb–Cl bond distances ranging from 2.51–2.96 Å. There are five inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Sb3- atom. In the second Cl1- site, Cl1- is bonded in a bent 150 degrees geometry to two equivalent Sb3- atoms. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Sb3- atom. In the fourth Cl1- site, Cl1- is bonded in a single-bond geometry to one Sb3- atom. In the fifth Cl1- site, Cl1- is bonded in a single-bond geometry to one Sb3- atom.
