A new mixed-metal polyborate, Na5Li[B12O18(OH)6]·2H2O (1), has been synthesized using solvothermal method and characterized by IR spectroscopy, thermogravimetric analysis, UV–Vis spectroscopy, powder and single-crystal X-ray diffraction, respectively. It crystallizes in the trigonal space group R-3c (No. 167) with unit cell parameters of a = b = 9.6767(6) Å, c = 36.358(5) Å, and Z = 6. Its structure...
The hydrothermal reaction of zinc ions with 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP) in the presence of additives such as 1,4-diazabicyclo[2.2.2]octane (DABCO), 1,3-propanediamine, imidazole and isonipecotic acid, afforded five metal phosphonates, namely, [H2DABCO]{Zn3[CH3C(OH)(PO3)2]2} (1), [C3H14N2]{Zn3[CH3C(OH)(PO3)2]2} (2), [C3H5N2]2{Zn3[CH3C(OH)(PO3)2]2} (3), {Zn2[CH3C(OH)(PO3)2][C3H4...
