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, Pna2(1) (No. 33), a = 9.148(3) angstrom, b = 7.596(3) angstrom, c = 5.500(2) angstrom, Z = 4, V = 382.2(2) angstrom(3), rho(caled) = 2.509 Mg/m(3), mu = 6.290 mm(-1), 3.49 < 0 < 27.51 T = 293 K, R-1 = 0.029, wR(2) = 0.0773 for 697 (I > 2 sigma(I)) of 1728 [R-(int) = 0.0246] unique reflections and 59 parameters. GOF = 1.073. Interestingly this basic zinc nitrate, [Zn(OH)(NO3)],, behaves well at removal capacity for hydrogen chloride gas, 20.3g HCl/100g, and its framework is not destroyed yet. This adsorption character may be useful for the removal of toxic gases in the environment. (c) 2006 Elsevier Inc. All rights reserved.
