title: Hexa-kis-(4-acetyl-pyridinium) octa-deca-chloridotetra-anti-monate(III).
abstract: The title compound, (C(7)H(8)NO)(6)[Sb(4)Cl(18)], contains centrosymmetric hexa-anions built up from four vertex-sharing alternating SbCl(5) square-based pyramids and highly distorted SbCl(6) octa-hedra when long (<3.2 Å) 'secondary' Sb-Cl inter-actions are taken into account. The inter-polyhedral Sb-Cl bonds define a square-shape. In the crystal, the components are linked by N-H⋯Cl, C-H⋯Cl and C-H⋯O hydrogen bonds, generating a three-dimensional network.
