Abstract: Single crystals of lead(II) chloride perrhenate(VII), (I), were obtained from a reaction of PbCl2 and Pb(ReO4)2. Its structure can be considered as an alternation of lead-chlorine slices, [Pb2Cl2]2+, formed of edge-sharing ClPb4 tetrahedra, and double layers of perrhenate anions, [ReO4-]2. Except for one O atom, all other atoms in (I) are situated on mirror planes. The arrangement is derived from a distorted matlockite (PbFCl) structure by replacing F with Cl, and introducing the ReO4 group instead of Cl. The structure of (I) is the first PbFCl derivative containing tetrahedral anions.
