Abstract:
In the title compound, [CuMoO(4)(C(8)H(20)N(4))]·H(2)O, the Cu(II) atom is coordinated by four N atoms of the 1,4,7,10-tetra-aza-cyclo-dodecane (cyclen) ligand and one O atom of the molybdate unit in a distorted square-pyramidal environment. The water mol-ecules 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 inter-actions. Additionally, the complex mol-ecules are linked into C(4) (4)(18) chain motifs by N-H⋯O inter-actions. As a result [(cyclen)CuMoO(4)] 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.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
