The Novel Polymorphic Form of Bis(3,5,7-triaza-1-azoniatricyclo[3.3.1.13,7]decane)‎ bis(μ4-oxo)‎-tris(μ3-oxo)‎-nonakis(μ2-oxo)‎-nonaaqua-decaoxo-hepta-molybdenum-di-zinc(II)‎ dihydrate, Synthesis, and Properties

Abstract EN

The reaction of molybdophosphoric acid with zinc carbonate followed by addition of hmta leads to formation of a triclinic polymorph of bis(3,5,7-triaza-1-azoniatricyclo[3.3.1.13,7]decane) bis(μ4-oxo)-tris(μ3-oxo)-nonakis(μ2-oxo)-nonaaqua-decaoxo-hepta-molybdenum-di-zinc(II) dihydrate in a one pot simple reaction.

The obtained compound has been characterised by IR, UV-Vis spectroscopy, elemental analysis, and X-ray crystallography.

A detailed comparison between both polymorphic forms: triclinic a=22.758 Å, b=24.702 Å, c=31.995 Å, α=101.206°, β=103.256°, γ=105.736°, and V=16203.8 Å3 and monoclinic a=43.120 Å, b=12.399 Å, c=16.285 Å, α=90.00°, β=111.12°, γ=90.00°, and V=8122 Å3 was performed.

The influence of the synthesis procedure on polymorph formation was described.
