Synthesis and Crystal Structure of Two Novel Tungstotellurates with Metal-Organic Complex Moieties

Abstract

Two novel tungstotellurates with metal-organic complex moieties have been synthesized. The polyoxometalates Na 2 (C 2 H 8 N 2 ) {[Ni(C 2 H 8 N 2 ) 2 (H 2 O)] 2 [Te 0.8 W 6.2 O 24 ]} · 8H 2 O(1) and [Na(H 2 O) 4 ] 2 {[Cu(C 2 H 8 N 2 ) 2 ] 2 [Te 0.8 W 6.2 O 24 ]} · 4H 2 O(2) were characterized by elemental analyses, IR spectroscopy, and single-crystal diffraction. The X-ray structure analysis reveals that these compounds both contain Anderson-Evans type anions.
