✦ Synopsis

compound (III) crystallizes in the monoclinic space group P2 1 /c with Z = 2 (single crystal XRD). The structure contains oligomeric tetrahedral anions based on six-membered rings of four BO 4 and two PO 4 tetrahedra with additional branchings by hydrogenphosphate groups (two cyclic, four open branches). Cu 2+ is in tetragonal pyramidal and K + in an irregular coordination by eight and nine oxygen atoms, respectively.
