Abstract

The solution-mediated syntheses and single crystal structures of (C6N2H10Zn)-Zn-.(HPO3)(2) (I) and (C6N2H8)(0.5)(ZnHPO3)-Zn-. (II) are reported. Slight variation of the synthesis conditions led to two quite different phases. I contains infinite chains of ZnO4 and HPO3 groups with the protonated organic moiety acting as a template and interacting with the chains by N-(HO)-O-... hydrogen bonds and possible C-(HO)-O-... interactions. In II, the neutral 1,4-diamino benzene molecule bonds to Zn (as a ligand) and an unusual composite, "pillared", structure results, with the organic species bridging 6(3) polyhedral sheets, although N-(HO)-O-... bonds are also present. Similarities and differences to other zinc phosphites and phosphates are briefly discussed for I and II. Crystal data: C6N2H10-Zn(HPO3)(2), M-r = 335.48, monoclinic, C2/c (No. 15), a = 17.2471 (14) Angstrom, b = 9.0720 (8) Angstrom, c = 7.6529 (6) Angstrom, beta = 103.752 (2)degrees, V = 1163.09 (7) Angstrom(3), Z = 4, R(F) = 0.038, wR(F-2) = 0.084. (C6N2H8)(0.5)(ZnHPO3)-Zn-., M-r = 199.42, orthorhombic, Pbca (No. 61), a = 8.0314 (16) Angstrom, b = 8.1299 (16) Angstrom, c = 18.830 (4) Angstrom, V = 1229.5 (4) Angstrom(3), Z = 8, R(F) = 0.026, wR(F-2) = 0.055.
