The new vanadoborate-supported hexanuclear zinc complex [Zn(teta)] _6[(VO)_(12)O_6B_(18)O_(36)(OH) _6](H_2O).8H_2O

摘要

The new vanadoborate-supported zinc complex [Zn(teta)]_6[(VO) _(12)O_6B_(18)O_(36)(OH)_6](H _2O).8H_2O (1, teta = triethylenetetramine) was synthesized hydrothermally and characterized by elemental and thermogravimetric analysis, and IR and UV/Vis spectroscopy. Complex 1 crystallizes in the trigonal system in space group R 3 and consists of the neutral [Zn(teta)]_6[(VO) _(12)O_6B_(18)O_(36)(OH)_6](H _2O) cage aggregate that is built up from a [(VO)_(12)O _6B_(18)O_(36)(OH)_6]~(12) cluster decorated with six [Zn(teta)]~(2+) complex groups, and a water molecule occupying the center of the cluster cage.
