Sumario: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-octa­hedral 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 inter­actions are considered, the eight-coordinate geometry is based on a dodeca­hedron. 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 inter­actions.
