Structure-Directing Weak Interactions with 1,4-Diiodotetrafluorobenzene Convert One-Dimensional Arrays of [MII(acac)2] Species into Three-Dimensional Networks

“…In the context of the M···C contacts, we conducted an extensive literature search for similar contacts in 1,3-diketonate metal complexes, and our results are summarized in Table 3S, Supporting Information. We found that in some works, performed mostly for copper­(II) complexes ,− and more rarely for palladium­(II) species, ,− short M···C (M = Cu II , Pd II ) contacts between metal centers and the central C atom of 1,3-diketonate ligands were recognized (Figures and ). The first reports appeared more than 50 years ago, , and the observed contacts were named “long intermolecular bond” and “weak interaction”, while later ,,− they were characterized as “notably short contacts”, “π–π stacking interactions involving chelate rings”, etc.…”

Self-assembled one-dimensional soft nanostructures

“…Over the past few decades, many studies have been carried out regarding coordination polymers and crystal engineering of metal complexes; selective metal ion binding has been found to be a promising approach to control the fabrication of nanoscale self-assembled structures. In metal coordinated structures, metal ion functioning had been used along with some other noncovalent interactions [45][46][47][48] including hydrogen bonding, p-p Fig. 1 A is the SEM image of the sac membrane after forming for 30 min.…”

Hydrogen-bond-driven self-assembly of bis(3-benzylpentane-2,4-dionato)(nicotinamide)copper(II) in the solid state

“…The self-assembly of the bis(3-benzylpentane-2,4-dionato)copper(II) complex Cu[(Bzl)acac] 2 is driven by weak C-HÁ Á ÁO hydrogen bonding andstacking (Judaš & Kaitner, 2006). A suitable bifunctional ligand that would bind to the Cu II ion and also participate in intermolecular hydrogen bonding is expected to affect the morphology of the crystal.…”
