Abstract
Two novel organically templated zincophosphites, [C 6H 22N 4] 0.5⋅[Zn 2(HPO 3) 3] and [C 3N 2H 5]⋅[Zn 1.5(HPO 3) 2] were synthesized using triethylenetetramine and imidazole as templates and characterized by single-crystal X-ray diffraction. [C 6H 22N 4] 0.5⋅[Zn 2(HPO 3) 3] crystallizes in monoclinic P - 1 with cell parameters a = 7.6468 ( 6 ) Å , b = 8.4084 ( 6 ) Å , c = 12.3097 ( 6 ) Å , and α = 70.488 ( 4 ) ° , β = 73.687 ( 4 ) ° , γ = 64.772 ( 4 ) ° . [C 3N 2H 5]⋅[Zn 1.5(HPO 3) 2] crystallizes in monoclinic C 2 / c with cell parameters a = 10.3397 ( 6 ) Å , b = 14.7632 ( 6 ) Å , c = 13.7726 ( 7 ) Å , and β = 100.734 ( 5 ) ° . Two zincophosphites consist of alternatively linked ZnO 4 tetrahedra and [ HPO 3 2 − ] pseudo pyramidal units. [C 6H 22N 4] 0.5⋅[Zn 2(HPO 3) 3] has two-dimensional structure and possesses a triple unit of 4-membered ring building-unit. [C 3N 2H 5]⋅[Zn 1.5(HPO 3) 2] has three-dimensional structure and imidazole cations are located in the 12-membered ring channel systems. Both of the compounds were also characterized by IR spectroscopy, thermogravimetric and differential thermal analyses.
