Abstract

{[Cu₄(µ₃-OH)₂(SIP)₂(imz)₂]·(H₂O)₂}_n (1) and {[Zn₃(µ₂-OH₂)₂(SIP)₂(phen)₃(H₂O)₃]·(H₂O)₅}_n (2) were obtained under hydrothermal conditions (SIP = 5-sulfoisophthalate, imz = imidazole, and phen = 1,10-phenanthroline). Compound 1 features a novel 3D network based on tetranuclear [Cu₄(µ₃-OH)₂] secondary building unit; its topological structure is similar to that of rutile. Compound 2 is a 1D zigzag chain containing dinuclear [Zn₂(µ₂-OH₂)₂(phen)₂] and mononuclear [Zn(phen)(H₂O)] units. Variable-temperature magnetic studies reveal the existence of dominant ferromagnetic interactions within the tetranuclear copper(ii) cluster in compound 1. Further magnetic measurements indicate that compound 1 has the zero-field splitting parameters D = –0.29 cm^–1 and E = 0.00052 cm^–1, and g = 2.11 based on S_T = 2. Compound 2 exhibits a blue fluorescence emission band at 458 nm on excitation at 391 nm, with a lifetime of 5.78 ns.
