Abstract Synthesis and structure of a supramolecular dimer and inorganic-organic cocrystal of composition [\CuIIL1< subset of>(H2O)\2(C8H6O4)] (1) are described (H2L1= N,N -ethylenebis(3-ethoxysalicylaldimine); C8H6O4 = terephthalic acid). Crystal engineering has been utilized for the designed synthesis of the title compound. Compound 1 crystallizes in a triclinic system with P1 space group. The structure consists of terephthalic acid and two symmetry related inclusion products [CuIIL1< subset of>(H2O)], in which the water molecule is encapsulated in the O4 compartment by forming bifurcated hydrogen bonds involving two hydrogen of water and phenolate and ethoxy oxygens of the compartmental ligand. Hydrogen bonding between encapsulated water molecules and terephthalic acid forms the supramolecular dimer. The title compound is an example of an inorganic-organic cocrystal as well. Weak interactions, such as semicoordination of phenoxo oxygen of one unit to the metal center of a symmetry related unit and C-H center dot center dot center dot O, and O-H center dot center dot center dot O hydrogen bonds result in generation of an overall 3-D topology in the title compound. The 3-D topology can be understood as interlinking of two different 2-D sheets.
