The Ni 3(PO 4) 2·8H 2O crystal crystallizes in the monoclinic system, space group C2/m , with M=128.13, a =0\^994 7(2) nm, b =1.321 7(3) nm; c =0.463 6(1) nm; β=104.80(3)°, V =0.589 3(2) nm 3, Z=2, R=0.027 2 and wR =0.057 5. The network structure consists of vertex sharing which results in the formation of undulating 4 ring chains and 8 ring sheets.展开更多

The title compound crystallizes in a hexagonal system, space group P6 3, with a= 0.950 23(5) nm, b=0.950 23(5) nm, c=1.694 2(2) nm, α=90°, β=90°, γ=120°, V=1.324 8(2) nm 3, Z=8, structure refined to R=0.052 8 and wR=0.116 5 for 2 134 independent observed reflections. The three-dimensional network structure consists of helical chains formed by apex-sharing polyhedra. The connection of the chains results in 4- and 8-polyhedral rings and cages centered by three indium metal connecting oxygen atoms formed by three 4-rings. The three-connected oxygen atom is firstly observed in indium phosphate systems.展开更多
