Odd-even alternation in molecular structure and self-assembling of some macrocyclic polyethers

Antimicrobial V-Shaped Copper(II) Pentaiodide: Insights to Bonding Pattern and Susceptibility

“…Macrocyclic ethers are examples of such good complexing agents and have many applications in different fields [ 20 , 21 , 53 , 54 , 55 ]. The crown ether molecules stabilize the anionic structure around the sandwiched central metal cations due to their selective binding mechanisms [ 20 , 21 , 52 , 53 , 54 , 55 ]. Their similarity to antibiotics makes them attractive models for drug interactions and cation transport across cell membranes [ 53 ].…”

Their similarity to antibiotics makes them attractive models for drug interactions and cation transport across cell membranes [ 53 ]. Their interaction with ions influences their molecular structure; 1,4,7,10-tetraoxacyclododecane (12-crown-4), a crown ether, forms stable tri- and pentaiodides [ 20 , 21 , 52 , 53 , 54 , 55 ].…”

Different stacking orders and a number of conformations arise from their immediate surrounding in liquid and solid states [ 53 , 54 , 55 ].…”

“…Different stacking orders and a number of conformations arise from their immediate surrounding in liquid and solid states [ 53 , 54 , 55 ]. According to computational investigations, 12-crown-4 self-aggregates with parallel layers of dipoles [ 53 ]. This arrangement results in weak hydrogen bonds between the C-O of one crown ether with the hydrogen atoms of a neighboring one [ 53 ].…”
