Of the four remaining unique CuII atoms, three adopt CuN2O2Cl square-pyramidal coordination geometries with the chloride ion in the apical position and one has a distorted CuN2OCl tetra-hedral geometry. The dianionic nona-nuclear core can be described as a 24-membered [CuNN]8 ring that contains a Cu9O6Cl6 core. The cluster features three intra-molecular O-H⋯Cl hydrogen bonds. In the crystal, weak C-H⋯N and C-H⋯Cl inter-actions link the components. Polynuclear paramagnetic clusters of this type are of considerable inter-est due to their relevance to both the bioinorganic and single-mol-ecule magnets research fields.The crystal structure of thallium(I) catena-polyphosphate, TlPO3, contains a polyphosphate chain extending parallel to [010] with a repeating unit of two phosphate tetra-hedra. The TlI atom is located in-between the polyphosphate chains and is bonded by oxygen atoms in a distorted [6 + 1] coordination in the form of a monocapped prism, with the longest Tl-O bond to the bridging O atom of the polyphosphate chain. A qu-anti-tative structural comparison with isotypic RbPO3 and CsPO3 reveals that the usually pronounced stereoactivity of the 6s2 lone pair at the TlI atom is not apparent in the case of TlPO3.During systematic investigations on the synthesis of coordination polymers with Co(NCS)2 involving different thio-urea derivatives as
