Abstract > Let H <sub> n </sub> be a linear crossed hexagonal chain with n crossed hexagonals. In this article, we find that the Laplacian (resp. normalized Laplacian) spectrum of H <sub> n </sub> consists of the eigenvalues of a symmetric tridiagonal matrix of order 2 n ?+?1 and a diagonal matrix of order 2 n ?+?1. Based on the properties of these matrices, significant closed formulas for the Kirchhoff index, multiplicative degree‐Kirchhoff index and the number of spanning trees of H <sub> n </sub> are derived. Finally, we show that the Kirchhoff (resp. multiplicative degree‐Kirchhoff) index of H <sub> n </sub> is approximately one quarter of its Wiener (resp. Gutman) index. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden"
