Di(1<i>H</i>-tetrazol-5-yl)methane as Neutral Ligand in Energetic Transition Metal Complexes
The
synthesis of diÂ(1<i>H</i>-tetrazol-5-yl)Âmethane (<b>1</b>, 5-DTM), starting from commercially available sodium azide and malononitrile,
is described. This tetrazole was characterized and investigated for
use as a neutral nitrogen-rich ligand in various energetic transition
metal complexes: ([CuCl<sub>2</sub>Â(5-DTM)<sub>2</sub>]·​2H<sub>2</sub>O (<b>2</b>), [CoÂ(H<sub>2</sub>O)<sub>2</sub>Â(5-DTM)<sub>2</sub>]ÂCl<sub>2</sub> (<b>3</b>), [NiÂ(H<sub>2</sub>O)<sub>2</sub>Â(5-DTM)<sub>2</sub>]ÂCl<sub>2</sub> (<b>4</b>), [CoÂ(H<sub>2</sub>O)<sub>2</sub>Â(5-DTM)<sub>2</sub>]Â(NO<sub>3</sub>)<sub>2</sub> (<b>6</b>), [NiÂ(H<sub>2</sub>O)<sub>2</sub>Â(5-DTM)<sub>2</sub>]Â(NO<sub>3</sub>)<sub>2</sub> (<b>7</b>), [ZnÂ(H<sub>2</sub>O)<sub>2</sub>Â(5-DTM)<sub>2</sub>]Â(NO<sub>3</sub>)<sub>2</sub> (<b>8</b>), {[Cu<sub>3</sub>Â(SO<sub>4</sub>)<sub>2</sub>Â(5-DTM<sub>–H</sub>)<sub>2</sub>Â(H<sub>2</sub>O)<sub>4</sub>Â(5-DTM)<sub>2</sub>]·​2H<sub>2</sub>O}<sub>∞</sub> (<b>9</b>), [CuÂ(H<sub>2</sub>O)<sub>2</sub>Â(5-DTM)<sub>2</sub>]Â(NO<sub>3</sub>)<sub>2</sub> (<b>11</b>), [CuÂ(NO<sub>3</sub>)<sub>2</sub>Â(5-DTM)<sub>2</sub>]·​2H<sub>2</sub>O (<b>12</b>), [CuÂ(NO<sub>3</sub>)<sub>2</sub>Â(5-DTM)<sub>2</sub>] (<b>13</b>), [CuÂ(H<sub>2</sub>O)<sub>2</sub>Â(5-DTM)<sub>2</sub>]Â(ClO<sub>4</sub>)<sub>2</sub> (<b>14</b>), and [CuÂ(ClO<sub>4</sub>)<sub>2</sub>Â(5-DTM)<sub>2</sub>] (<b>15</b>). Obtained coordination
compounds were characterized using single crystal X-ray diffraction
(except for <b>7</b> and <b>13</b>), IR spectroscopy,
elemental analysis, and differential thermal analysis. The sensitivities
to external stimuli (impact, friction, electrostatic discharge) were
determined. Complexes <b>12</b> and <b>13</b> were tested
for their ignitability by laser irradiation
