The products of the solid-state reactions between potassium metal and tetracene (K:Tetracene, 1:1, 1.5:1, and 2:1) are fully structurally characterized. Synchrotron X-ray powder diffraction shows that only K<sub>2</sub>Tetracene forms under the reaction conditions studied, with unreacted tetracene always present for <i>x</i> < 2. Diffraction and <sup>13</sup>C MAS NMR show that K<sub>2</sub>Tetracene has a crystal structure that is analogous to that of K<sub>2</sub>Pentacene, but with the cations ordered on two sites because of the influence of the length of the hydrocarbon on possible cation positions. K<sub>2</sub>Tetracene is a nonmagnetic insulator, thus further questioning the nature of reported superconductivity in this class of materials.
