Research has been conducted on the copper molybdate family. The structures and magnetic properties of bimetallic oxides [Cu(3,4'-bpy)MoO (sub)4], [Cu(3,3'-bpy) (sub)0.5 MoO (sub)4], and [Cu(4,4'-bpy) (sub)0.5 MoO (sub)4].1.5H (sub)2 O have been studied and the details are presented.

Results reveal that the new series of germanium antimonides are metallic and those containing RE = Nd, Sm, Gd-Dy exhibit kinks in their temperature resistivity behavior. Further, the compounds reveal long-range antiferromagnetic ordering in their atomic structures.

The structural characterization of a new series of germanium antimonides show that the rare-earth atom trigonal prism columns are separated by Ge and Sb atoms. The atoms exhibit interactions between them ranging from strong covalent bonds to intemediate partial bond to weak van der Waals forces.

A study is conducted on the nonstoichiometric ternary arsenide Ba0.8Hf12As17.7. The compound was synthesized by reacting the elements at 950 degrees Centrigrade in a tin flux. It is shown that Ba0.8Hf12As17.7 exhbits the unique feature of As ribbons inserted between isolated columnar assemblies of Hf6 trigonal prisms. The behavior and features of As-As bonding in Ba0.8Hf12As17.7 were also determined using extended Huckel band structure calculations.

The new Zintl phase Ba2Sn3Sb6 was synthesized and its structure was analyzed. Its structure is composed of large channels constructed from an anionic framework built up from Sn-centered trigonal pyramids and tetrahedra, as well as zigzag chains of Sb atoms. Ba2+ cations and additional isolated zigzag Sb-Sb chains were found within the channels. Ba2SnSb6 is a mixed-valence compound containing both tin(II) and tin(IV).

The preparation of a new series of organic-inorganic materials of the oxovanadium/organophosphonate/M(II)-organoimine family is allowed by hydrothermal synthesis. The report stated that the hybrid materials exhibited a range of magnetic properties, reflecting the presence of a single type paramagnetic metal ion Cu(II) and two distinct paramagnetic ions Cu(II) and V(IV).
