A new coordination polymer formulated as [C{sub 8}H{sub 10}CdO{sub 7}]{sub n}.4H{sub 2}O has been prepared via a hydrothermal procedure by using 1,4-benzenedicarboxylic (p-BDC) and Cd{sup II} salt as starting materials. The structure was determined by single-crystal X-ray diffraction and the result shows that the complex crystallizes in orthorhombic system, space group Pcca, with M{sub r}=402.62, a=7.293(2) A, b=9.980(3) A, c=19.889(6) A, V=1447.6(8) A{sup 3}, Z=4, D{sub c}=1.847 g/cm{sup 3}, F(000)=808, {mu}(MoK{alpha})=1.559 mm{sup -1}, R=0.0478, wR=0.1150, GOF=1.199. It displays a neutral layered framework along ab plane constructed by hydrogen-bonding interaction through infinite zigzag chains. Its thermal decomposition and solid-state transformation course between 30 and 550 deg. C was recorded by TG curve and XRD pattern, respectively. Interestingly, it is found that at higher temperature the crystal material was converted to uniform CdO nanowires, suggesting an effective and reasonable complex-precursor procedure for preparing one-dimensional crystalline nanomaterials. - Graphical abstract: 1D CdO nanowires have been prepared by an effective and reasonable complex-precursor procedure, in which a layered metal-organic framework assembled by 1D infinite zigzag chains was heated in the presence of oxygen at higher temperature.
