%0 Journal Article %T On the symmetry of bis benzene cromium(0) with D6d point group %A Hamadanian %A M. %A Reza Ashrafi %A A. %J Anales de la Asociaci£¿3n Qu£¿-mica Argentina %D 2006 %I Scientific Electronic Library Online %X an euclidean graph associated with a molecule is defined by a weighted graph with adjacency matrix m = [dij], where for i¡Ù j, dij is the euclidean distance between the nuclei i and j. in this matrix dii can be taken as zero if all the nuclei are equivalent. otherwise, one may introduce different weights for distinct nuclei.in this paper, the automorphism group of the bis benzene chromium(0) with d6d point group symmetry is computed. we also find an euclidean graph with an odd number of automorphisms. this solved a problem posed by the author in an earlier paper. %U http://www.scielo.org.ar/scielo.php?script=sci_abstract&pid=S0365-03752006000200005&lng=en&nrm=iso&tlng=en
