Towards rational design of zinc(ii) and cadmium(ii) sulfonate-arsonates with low dimensional aggregations

Abstract

Hydrothermal reactions of zinc(II) or cadmium(II) salts with o-sulfophenylarsonic acid (o-HO3S-C6H4-AsO3H2, H3L) afforded two layered compounds, namely, [Zn2(L)(OH)(H2O)]·H2O (1) and [Cd3(L)2(H2O)3]·H2O (2). Introduction of 2,2′-bipyridine (bipy), 1,10-phenanthroline (phen), and 2,2′:6′,2′′-terpyridine (terpy) as auxiliary chelating ligands led to a series of zinc(II) or cadmium(II) sulfonate-arsonates with lower dimensional aggregations, namely, [Zn(HL)(bipy)2]2·6H2O (3), [Cd(HL)(bipy)]2 (4), [Zn(HL)(phen)]2·2H2O (5), [Cd(HL)(phen)(H2O)]2[Cd(HL)(phen)]2 (6), [Cd(HL)(phen)]2·2H2O (7), [Zn(HL)(terpy)]2 (8), [Cd(HL)(terpy)]2·2H2O (9), Zn(HL)(bipy) (10), Zn(HL)(bipy)·2H2O (11), and Zn(HL)(phen)·H2O (12). Compound 3 contains two mononuclear cluster units, whereas 4–9 feature five types of dinuclear cluster units in which a pair of Zn2+ or Cd2+ ions are interconnected by two sulfonate-arsonate ligands (via M–O–M, M–O–As–O–M and M–O–S–O–M bridges). Compounds 10 and 11 feature a one-dimensional (1D) chain in which each pair of Zn2+ centers are bridged by one arsonate group of a sulfonate-arsonate ligand. In compound 12, dinuclear clusters and 1D chains coexist. All twelve compounds display very strong fluorescence in the ultraviolet or blue light region.
