- Abstract
In the reaction of a heterometallic complex of the composition [Li2Zn2(piv)6(py)2] (piv− is the pivalate anion, py is pyridine) with 2,5-pyridinedicarboxylic acid (H2pdc) and 4,4′-bipyridyl (4,4′-bpy), molecular complex [Zn(MeOH)2(Hpdc)2]·4,4′-bpy (1) is obtained. In the interaction of the same complex with another dicarboxylic acid (1,4-naphthalenedicarboxylic (H2ndc)) and also in the presence of 4,4′-bipyridyl, heterometallic metal-organic framework (MOF) [{LiZn}4(4,4′-bpy)(dmf)2(ndc)6]·3DMF·H2O (2) is formed. In the interaction of a polymeric pivalate complex of the composition [Cd2Eu(piv)7(H2O)2]·nMeCN with thiophenedicarboxylic acid (H2tdc), layered MOF (Me2NH2)2[Cd(tdc)2]·1.5DMF·H2O is obtained (3). The structures of 1–3 are determined by single crystal X-ray diffraction. In the reactions studied, the structures of initial heterometallic {Li2Zn2} and {Cd2Eu} moieties is partially retained only for MOF 2. This coordination polymer is of interest for the study of luminescent and sorption properties. In the other cases, the heterometallic unit is fragmented, which results in the formation of a final product involving only one of two metal cations contained in the initial unit.
