Abstract
Structure-based topological descriptors of chemical networks enable us the prediction of physico-chemical properties and the bioactivities of compounds through QSAR/QSPR methods. Topological indices are the numerical values to represent a graph which characterises the graph. One of the latest distance-based topological index is the Mostar index. In this paper, we study the Mostar index, Szeged index, PI index, <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" id="M1"><a:msub><a:mrow><a:mtext>ABC</a:mtext></a:mrow><a:mrow><a:mtext>GG</a:mtext></a:mrow></a:msub></a:math> index, and <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" id="M2"><c:mtext>NGG</c:mtext></c:math> index, for chain oxide network <e:math xmlns:e="http://www.w3.org/1998/Math/MathML" id="M3"><e:msub><e:mrow><e:mtext>COX</e:mtext></e:mrow><e:mrow><e:mi>n</e:mi></e:mrow></e:msub></e:math> , chain silicate network <g:math xmlns:g="http://www.w3.org/1998/Math/MathML" id="M4"><g:msub><g:mrow><g:mtext>CS</g:mtext></g:mrow><g:mrow><g:mi>n</g:mi></g:mrow></g:msub></g:math> , ortho chain <i:math xmlns:i="http://www.w3.org/1998/Math/MathML" id="M5"><i:msub><i:mrow><i:mi>S</i:mi></i:mrow><i:mrow><i:mi>n</i:mi></i:mrow></i:msub></i:math> , and para chain <k:math xmlns:k="http://www.w3.org/1998/Math/MathML" id="M6"><k:msub><k:mrow><k:mi>Q</k:mi></k:mrow><k:mrow><k:mi>n</k:mi></k:mrow></k:msub></k:math> , for the first time. Moreover, analytically closed formulae for these structures are determined.
