چکیده
The title complex, {[Ni(C(7)H(7)N(4)O(2))]OH}(n), has been prepared through hydro-thermal synthesis. The asymmetric unit contains one [Ni(TH)](+) cation (TH is the theophylline anion) and one hydroxide anion. The Ni(2+) ion is coordinated by two N atoms from two neighboring theophylline anions. The alternating linkage of the Ni(2+) cation and theophylline anion results in a one-dimensional chain along the [010] direction. Intermolec-ular O-H⋯O hydrogen bonds are present n the crystal structure.

In the title crystal structure, [Cd(NCS)(NO(3))(C(11)H(9)N(5))](n), the unique Cd(II) ion is coordinated in a distorted penta-gonal-bipyramidal environment. The axial thio-cyanate ligands act in a μ(1,3)-bridging mode to connect symmetry-related Cd(II) ions into one-dimensional chains along [010]. In addition, there are inter-molecular C-H⋯O contacts between chains.
