In molecular graphs, atoms are denoted by vertices and bonds by edges. In this paper, we focus on the molecular graph of (2D) silicon-carbon    S  i 2   C 3     -I and    S  i 2   C 3     -    I I    . Moreover, we have computed topological indices, namely general Randi\u0107 Zagreb types indices, geometric arithmetic index, atom\u2013bond connectivity index, fourth atom\u2013bond connectivity and fifth geometric arithmetic index of    S  i 2   C 3     -I and    S  i 2   C 3     -    I I    .<\/jats:p>","DOI":"10.3390\/sym10050173","type":"journal-article","created":{"date-parts":[[2018,5,21]],"date-time":"2018-05-21T04:07:30Z","timestamp":1526875650000},"page":"173","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":48,"title":["On Topological Properties of Symmetric Chemical Structures"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2827-0462","authenticated-orcid":false,"given":"Muhammad","family":"Imran","sequence":"first","affiliation":[{"name":"Department of Mathematical Sciences, United Arab Emirates University, P.O.
