Solvothermal synthesis and removal capacity for hydrogen chloride gas of Zn(OH)(NO3) with a rare (10,3)-d net

A basic zinc nitrate, [Zn(OH)(NO3)]n with a novel framework reported herein is prepared by solvothermal synthesis, and holds a rare three-dimensional (10,3)-d net called by Wells. It crystallizes in orthorhombic, space group, Pna21 (No. 33), a=9.148(3)Å, b=7.596(3)Å, c=5.500(2)Å, Z=4Z=4, V=382.2(2)Å3, ρcalcd=2.509Mg/m3, μ=6.290mm-1, 3.49<θ<27.513.49<θ<27.51, T=293K, R1=0.029R1=0.029, wR2=0.0773wR2=0.0773 for 697 (I>2σ(I)I>2σ(I)) of 1728 [R(int)=0.0246R(int)=0.0246] unique reflections and 59 parameters. GOF=1.073. Interestingly this basic zinc nitrate, [Zn(OH)(NO3)]n behaves well at removal capacity for hydrogen chloride gas, 20.3 g HCl/100 g, and its framework is not destroyed yet. This adsorption character may be useful for the removal of toxic gases in the environment.
