Mononuclear and binuclear copper(II) complexes with bis(2-imidazolyl)(bis(methoxycarbonyl)methylmethane) (BIBM), a tripodal bis(imidazole) based ligand. Synthesis, crystal structure and magnetic Characterization of [Cu(BIBM)2](ClO4)2 and [{Cu(BIBM)(H2O)}2(μ1,2,3,4-C2O4)](C4O4)·6H2O

We present an experimental investigation of the structural and magnetic properties of Ho3SbO7 and Dy3SbO7. These compounds adopt the Y3TaO7 structure, space group C2221. The magnetic rare-earth ions occupy an intricate lattice related to the pyrochlore lattice that occurs in Ho2Ti2O7 and Dy2Ti2O7. The crystal structure of Ho3SbO7 is determined by Rietveld refinement of the powder X-ray diffraction pattern at ambient temperature, and that of the Dy analogue is inferred to be similar. Magnetic susceptibility measurements show that Ho3SbO7 and Dy3SbO7 have negative CurieWeiss temperatures: 8.4 K (Ho) and 9.2 K (Dy). Magnetic transitions have been detected at 2.0 K (Ho) and 3.0 K (Dy). We discuss the results in terms of the ``dipolar spin ice model'' that has been used to describe Ho2Ti2O7 and Dy2Ti2O7.

The Relationship

A new complex phosphate K1.84Fe1.42Nb0.58(PO4)3 has been synthesized by the self-flux technique. The X-ray single crystal structure and magnetic properties were studied. The compound crystallizes in the cubic system with space group P213 (a = 9.9404(10) Å ) and belongs to the langbeinite structure type. The structure contains [M2P3O18] building units. “Closed” fragments [M8P9O60] provide space for location of two potassium atoms. Antiferromagnetic interactions were detected at low temperatures which originate from superexchange through a M(1)-O-P-O-M(2) pathway with corresponding J = −5.5(1) cm−1. The relationship between the UV/vis absorption and the structure is discussed.
