Abstract Topological indices are the fixed numbers associated with the graphs. In recent years, mathematicians used indices to check the pharmacology characteristics and molecular behavior of medicines. In this article the first Zagreb connection number index is computed for the nanotubes VC5C7[ p, q] , HC 5 C 7[ p,q] and Boron triangular Nanotubes. Also, the same index is computed for the Quadrilateral section P m n $P_{m}^{n}$and P m+ 1 2 n $P_{m+\frac{1}{2}}^{n}$cuts from regular hexagonal lattices.
