We report our results on two ternary intermetallic compounds ${\text{Pr}}_{2}{\text{Pd}}_{3}{\text{Ge}}_{5}$ and ${\text{Pr}}_{2}{\text{Rh}}_{3}{\text{Ge}}_{5}$ based on magnetic susceptibility, magnetization, specific heat, resistivity, and magnetoresistance data. These compounds form in ${\text{U}}_{2}{\text{Co}}_{3}{\text{Si}}_{5}$-type orthorhombic structure (space group Ibam). ${\text{Pr}}_{2}{\text{Pd}}_{3}{\text{Ge}}_{5}$ exhibits two magnetic transitions at ${T}_{N1}=7.5\text{ }\text{K}$ and ${T}_{N2}=8.3\text{ }\text{K}$. In the magnetically ordered state, ${\text{Pr}}_{2}{\text{Pd}}_{3}{\text{Ge}}_{5}$ …
