Abstract
The synthesis of two new lead(II) coordination polymers, [Pb2(picOH)4] .H2O (1) and [Pb3(Sip)2- (H2O)2] .H2O (2) has been reported, where HpicOH = 3-hydroxypicolinic acid and NaH2Sip = 5-sulfoi- sophthalic acid monosodium salt .Both the complexes were structurally characterized by X-ray single crystal diffraction analysis.Complex 1, where the 3-hydroxypicolinate ligand is used for the first time in conjunction withPb(II), revealed to bea1D polymericarray. Complex 2 showed a 3D structure with 5-sulfoisophthalate ligand adopting two novel binding modes of high denticity (eta-6mu-6 and eta-7mu-7). The photoluminescence and thermal properties of the two complexes have been studied.Pubblicazioni consigliate
