Abstract

In our effort to explore the use of the sulfite ion to design hybrid and open-framework materials, we have been able to prepare, under hydrothermal conditions, zero-dimensional [Zn(C12H8N2)(SO3)].2H2O, I (a = 7.5737(5) A, b = 10.3969(6) A, c = 10.3986(6) A, alpha = 64.172(1) degrees , beta = 69.395(1) degrees , gamma = 79.333(1) degrees , Z = 2, and space group P), one-dimensional [Zn2(C12H8N2)(SO3)2(H2O)], II (a = 8.0247(3) A, b = 9.4962(3) A, c = 10.2740(2) A, alpha = 81.070(1) degrees , beta = 80.438(1) degrees , gamma = 75.66(5) degrees , Z = 2, and space group P), two-dimensional [Zn2(C10H8N2)(SO3)2].H2O, III (a = 16.6062(1) A, b = 4.7935(1) A, c = 19.2721(5) A, beta = 100.674(2) degrees , Z = 4, and space group C2/c), and three-dimensional [Zn4(C6H12N2)(SO3)4(H2O)4], IV (a = 11.0793(3) A, c = 8.8246(3) A, Z = 2, and space group P42nm), of which the last three are coordination polymers. A hybrid open-framework sulfite-sulfate of the composition [C2H10N2][Nd(SO3)(SO4)(H2O)]2, V (a = 9.0880(3) A, b = 6.9429(2) A, c = 13.0805(5) A, beta = 91.551(2) degrees , Z = 2, and space group P21/c), with a layered structure containing metal-oxygen-metal bonds has also been described.
