title: Tripotassium bis-(acetato-κO,O')(thio-cyanato-κN)plumbate(II) dithio-cyanate.
abstract: In the crystal structure of the title salt, K(3)[Pb(CH(3)COO)(2)(NCS)](NCS)(2), the [Pb(CH(3)COO)(2)(NCS)](-) anion exists as a covalently bonded entity in which the acetate anions chelate in an anisobidentate manner. The Pb atom shows a distorted ψ-octa-hedral coordination to four acetate O atoms and one isocyanate N atom, with the stereochemically active lone pair occupying one of the six sites. When the three longer Pb⋯S inter-actions are considered, the eight-coordinate geometry is based on a dodeca-hedron. The Pb(CH(3)COO)(2)(NCS)](-) anion has mirror symmetry. The potassium cations connect the other constituents into a three-dimensional network through electrostatic K⋯N and K⋯S inter-actions.
