MnCl2(C6N10H6): Insights into a Luminescent Transition Metal–Melem Complex
In this work, the (MnCl<sub>2</sub>(C<sub>6</sub>N<sub>10</sub>H<sub>6</sub>) complex has been synthesized via solid-state reaction between manganese (II) chloride and melamine in the molar ratio of 1:2. A similar synthesis has been repeated with CoCl<sub>2</sub>, and FeCl<sub>2</sub>, resulting in two new metal-melam complexes (FeCl<sub>2</sub>(C<sub>6</sub>N<sub>11</sub>H<sub>9</sub>) and CoCl<sub>2</sub>(C<sub>6</sub>N<sub>11</sub>H<sub>9</sub>)). MnCl<sub>2</sub>(C<sub>6</sub>N<sub>10</sub>H<sub>6</sub>) crystallizes in the monoclinic crystal system with the space group <i>I</i>2/<i>a</i>. The crystalline powder of MnCl<sub>2</sub>(C<sub>6</sub>N<sub>10</sub>H<sub>6</sub>) was studied by X-ray diffraction, infrared spectroscopy, and thermogravimetric analysis to examine its structure and properties. MnCl<sub>2</sub>(C<sub>6</sub>N<sub>10</sub>H<sub>6</sub>) also shows good thermal stability up to 370 °C; however, the complete decomposition occurred at 900 °C, yielding Mn<sub>7</sub>C<sub>3</sub>. This paper presents an easy synthesis of the first luminescent transition metal-melem complex, providing new insights into the reactivity of melamine at elevated temperatures in the presence of transition metal chlorides.
