A mixed valent heterometallic Cu^II/Na^I coordination polymer with sodium-phenyl bonds

A mixed valent heterometallic Cu^II/Na^I coordination polymer (1) is generated by the reaction of a Schiff base ligand, (6,6′-(1E,1′E)-(2-hydroxypropane-1,3-diyl)bis(azan-1-yl-1-ylidene) bis(methan-1-yl-1-ylidene)bis(2-methoxyphenol)) with copper(ii) acetate and sodium perchlorate. In addition to the presence of alcohol oxygen-sodium coordination bonds, the single crystal X-ray structure reveals that the 1D coordination polymer is stabilised by the formation of phenyl-sodium η₂-bonds, face-to-face π-π contacts and Cu-π interactions.
