Abstract:

The stoichiometric reaction of 1,10-phenanthroline (phen), imino­di­acetic acid (IDA-H2) and Cu(ClO4)2 in a H2O–CH3OH (2:1) solution yields -imino­diacetato-2:14O,N,O′:O′′-tris(1,10-phenanthroline)-14N,N′;22N,N′-dicopper(II) diperchlorate methanol solvate, [Cu2(C4H5NO4)(C12H8N2)3](ClO4)2·CH3OH. The IDA ligand bridges the two CuII ions via a carboxyl­ate group and uses one further N and an O atom of the second carboxylate group to complete a fac-tridentate coordination at one Cu centre. A phen ligand completes a distorted square-pyramidal coordination at this metal atom, although there is weak coordination by a perchlorate O atom at a sixth position. The second Cu centre has a distorted trigonal–bipyramidal coordination to two phen moieties and a carboxyl­ate O atom.
