A new metal-organic complex formulated as [Co(ISOIN)2(H2O)4] 1 (H2ISOIN) = isonicotinic acid) has been synthesized by low-temperature solid-state reaction and characterized by single-crystal X-ray diffraction, elemental analyses, IR and UV-visible spectra. The strong intermolecular O-Hź ź źO hydrogen-bonds interactions are the most significant factors controlling the novel supramolecular sheet fashion packing of the title compound in the crystal state. The third-order non-linear optical (NLO) properties of 1 were also investigated and they exhibit the reverse saturable absorption and self-defocusing performance with modulus of the hyperpolarizability gamma 8.75×10-31 esu for 1 in a 1.56×10-4 molźdm-3 DMF solution.

A novel co balt(II) coordination polymer [Co(bpy)2(m2-S6)]n 1 (bpy = 2,2'-bipyridine) has been synthesized by low-tempera ture solid-state reaction. Single crystal X-ray analyses reveal that compound 1 pos sesses a new type of two-dimensional (2-D) frame work structure. Each Co(II) ion, located on an center of distorted octahedron, is six-coordinated by four nitrogen atoms from the bpy ligands and two sulfur atoms from the mi 2-S6 ligands. The compound 1 was characterized by elemental analyses, IR spectra and UV-visible spectra. The third-order non-linear optical (NLO) properties were also investigated and they exhibit good non-linear absorption and self-defocusing performance with modulus of the hyperpolarizability (gamma) 2.17×10–30 esu for 1 in a 1.7×10–4 mol×dm–3 DMF solution.

Acobalt(III) 8-hydroxyquinoline complex [Co(8-Q)3]0x5CH3OH1, (8-HQ = 8-hydroxyquinoline) has been synthesized by low-temperature solid-state reaction. Single crystal X-ray analyses revealed that compound 1 possesses a three-dimensional (3–D) supramolecular structure. Each Co ion is bridged by three 8-hydroxyquinoline ligands. The compound 1was characterized by elemental analysis, IR spectra and UV-visible spectra. The third-order nonlinear optical (NLO) properties were also investigated and they exhibit good nonlinear absorption and self-defocusing performance with modulus of the hyperpolarizability () 5.2310–30 esu for 1 in a 1.0610–4 moldm–3 DMF solution.
