摘要：

Compound CU2(H2O)(2){O3PCH2N(C2H4)(2)NCH2PO3} (1) has a pillared layered structure in which the organic groups of N, N'-piperazinebis(methylenephosphonate) are sandwiched between the inorganic layers. Compared with other copper phosphonates with layered or pillared layered structures, the inorganic layer in 1 is unique in that each {CPO3} tetrahedron is corner-shared with three {CuO4N} square pyramids through three oxygen donors. Ferromagnetic interactions are mediated between the metal centers. Crystal data: Pbca, a = 10.0830(16) Angstrom, b = 9.4517(15) Angstrom, c = 13.218(2) Angstrom, V - 1259.7(3) Angstrom(3), Z = 4.
