(1,4,7,10-Tetraazacyclododecane-κ4 N 1,N 4,N 7,N 10)(tetraoxidomolybdato-κO)copper(II) monohydrate

In the title compound, [CuMoO4(C8H20N4)]center dot H2O, the CuII atom is coordinated by four N atoms of the 1,4,7,10-tetraazacyclododecane (cyclen) ligand and one O atom of the molybdate unit in a distorted square-pyramidal environment. The water molecules are linked to the complex unit to form centrosymmetric dimers [R (4) 4(12) and R (4) 4(16)] and discrete D (3) 2(9), D (3) 3(11) and D (3) 3(13) chains by O-H...O and N-H...O interactions. Additionally, the complex molecules are linked into C (4) 4(18) chain motifs by N-H...O interactions. As a result [(cyclen)CuMoO4] units and water molecules are linked to layers that are oriented parallel to the ac plane. The stacking of the layers in the b-axis direction is supported by weak C-H...O hydrogen bridges.
