Abstract:	Synthesis, crystal engineering, and magnetic properties of an anionic 4-terpyridone (L) based three-dimensional supramolecule, [Cu2II(L)2(μ1,1-N3)2] · 2[CuII(L)(N3)(H2O)] · 6H2O (1), have been described in the present investigation. The title compound crystallizes in the monoclinic space group C2/c with the following unit cell parameters: a = 27.803(7) Å, b = 14.361(4) Å, c = 16.071(4) Å, β = 99.09(2)°, and Z = 4. In this compound, one dinuclear [Cu2II(L)2(μ1,1-N3)2] unit is cocrystallized with two mononuclear [CuII (L)(N3)(H2O)] units. In both the dinuclear and mononuclear species, 4-terpyridone chelates to the metal centers in its anionic form. The coordination environment of the metal ions is distorted square pyramidal. Eight O–H⋯O type strong hydrogen bonds involving the oxygen of anionic 4-terpyridone ligand and water molecules link the components of 1 into a three-dimensional framework. Excluding the atoms except the water molecules and ligand oxygens, the topology is a two-dimensional network. The mononuclear [CuII(L)(N3)(H2O)] moiety is appended from this sheet, while the neighboring sheets are interlinked by the dinuclear [Cu2II(L)2(μ1,1-N3)2] unit to add the third dimension of the overall three-dimensional structure of the title compound.
