Structural determination reveals that complex 1 is dinuclear, 2 is a 1D polymeric chain, while 3 is a three-fold interpenetrated α-polonium-like network. Hydrogen bonding interactions, formed by coordinated and/or lattice water molecules with ppda oxygen, and  staking interactions of aromatic rings lead to a 3D supramolecular architecture in both complexes 1 and 2. Low temperature magnetic study shows antiferromagnetic coupling in all the complexes. In addition, their electronic and fluorescent spectral properties have also been investigated.10 p.application/pdfeng(c) American Chemical Society , 2014Estructura cristal·lina (Sòlids)LligandsLayer structure (Solids)Ligandsinfo:eu-repo/semantics/article6431692020-05-04info:eu-repo/semantics/openAccess
