((CH3)2NH2)3SbCl5SbCl4 is Silicon tetrafluoride-derived structured and crystallizes in the monoclinic Pc space group. The structure is zero-dimensional and consists of six dimethylazanium molecules, two SbCl4 clusters, and two SbCl5 clusters. In each SbCl4 cluster, Sb3- is bonded in a rectangular see-saw-like geometry to four Cl1- atoms. There are a spread of Sb–Cl bond distances ranging from 2.43–2.67 Å. There are four 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 single-bond geometry to one Sb3- atom. 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 each SbCl5 cluster, Sb3- is bonded in a square pyramidal geometry to five Cl1- atoms. There are a spread of Sb–Cl bond distances ranging from 2.44–2.91 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 single-bond geometry to one Sb3- atom. 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 2-coordinate geometry to one Sb3- atom.
