X ray single crystal structure analysis indicates this compound crystallizes in the orthorhombic space group Pbca, a =1.605 6(7) nm, b = 1 011 4 (4) nm, c =1.854 6(5) nm, V =3.011 6(19) nm 3, Z =4. The three dimensional framework based on linkage of corner sharing polyhedron PO 4, GaO 4F and GaO 4F 2 delimit ten ring channels along b axis in which the triply protonated amines are located serving as charge compensating guests and supporters.展开更多

The crystal belongs to monoclinic, space group C2/m, a=2.0654(4)nm, b=1.3306(3)nm, c=1.3194(3)nm, β=119.59(3)°, V=3.1531(11)nm3, Dc=3.606Mg·m-3, Z=2, R=0.0462, Rw=0.0836. The title compound comprises of a 2+ unit, a polyanion and a free (CH3)2NH molecule. The ESR spectrum of the title compound shows that charge transfer between organic groups and polyanion takes place under irradiation of the sunlight in solid state. The TG study of the title compound shows that it had four stages of the weight loss, and the increase of the decomposition temperature for the polyanion shows that the stability of the polyanion was enhanced due to the influence of Zn2+ ion.

The structure contains the isolated polyanions of [Mo5O15(HPO4)2]4- units around which the portonated ethylenediamine ions are pos itioned. By hydrogen bond interactions the polyanions are interconnected to form a three dimensional network. Other characterizations by powder XRD, IR and thermal analysis are also described.
