Two structurally different polymorphs of cobalt(II) imidazolate frameworks are solvothermally synthesized by using
<i>N</i>,<i>N</i>-dimethylacetamide as a template: The polymorph <b>6</b> (<i>a</i> = 9.797 (4) Å, <i>b</i> = 15.301(6) Å, <i>c</i> =14.902(6) Å, β
= 98.904(6)°, monoclinic, <i>P</i>2<sub>1</sub>/<i>n</i>) shows structures of silicate CaAl<sub>2</sub>Si<sub>2</sub>O<sub>8</sub> with CrB<sub>4</sub> topology, while polymorph <b>7</b> (<i>a</i>
= 15.173(4) Å, <i>b</i> = 15.173(4) Å, <i>c</i> = 19.089(5) Å, <i>Pbca</i>) shows CaGa<sub>2</sub>O<sub>4</sub>-related topological structures. In addition,
the <b>7</b>‘ (<i>a</i> = 15.9712(18) Å, <i>b</i> = 15.9253(19) Å, <i>c</i> = 18.475(2) Å, <i>Pbca</i>), a compound isostructural with <b>7</b>, is
synthesized by using cyclohexanol as a template. Thus, these cobalt(II) imidazolate polymers are reminiscent of
the zeolite syntheses in that not only the same topological structure can be synthesized by using the different
organic templates, but also different topological structures can be synthesized by using the same organic template.
