Abstract

The hydrothermal reaction of Cu(SO₄)·5H₂O, methylenediphosphonate and water in the mole ratio 1.0:1.5:4100 at 150°C for 48 h yielded clear colorless crystals of [Cu₂(O₃PCH₂PO₃)] (1). The structure of 1 is a three-dimensional framework constructed from chains of edge-sharing {CuO₅} trigonal bipyramids linked through the {O₃PCH₂PO₃}^4- subunits. The magnetic data from 35 to 300 K were fit to the Heisenberg linear antiferromagnetic chain model, giving g = 1.98 and J/k_B = -35.9 K. At lower temperatures, a Néel transition suggests three-dimensional long-range ordering. Crystal data: CH₂Cu₂O₆P₂, orthorhombic, Pnma, a = 13.698(1), b = 8.0094(6), c = 4.8950(4) Å, V = 537.04(7) Å³, Z = 4, D_calc = 3.699 g cm^-3.
