We herein treat a bond-diluted mixed spin-5/2 and spin-1/2 transverse Ising polyhedral chain in terms of the finite cluster approximation. The impact of the concentration p and the transverse fields (Ωσ, Ωs) on the phase diagrams and magnetizations has been thoroughly examined. In particular, we have found that all transitions are of second order with the possibility of compensation behavior as well as horizontal reentrance. Interestingly, by applying a transverse field Ωs acting only on the S-sublattice, the order cannot be destroyed at low temperatures due to the order imposed in the pentagonal sublattice. In addition, enhancing defects by lowering the concentration p diminishes the second-order transition temperature, and may end at zero at a Ω-dependent critical bond percolation threshold pc.
