LaRh2Sn2 crystallizes in the centrosymmetric primitive tetragonal crystal structure
P4/mmm (number 123)  commonly referred to as the CaBe2Ge2-type which was confirmed on
our synthesized samples by x-ray diffraction. The existence of this superconducting transition
was published  and in this study we proceed with an extensive study into the properties of this
superconducting ground state using physical property measurements. Electrical resistance and
heat capacity measurements reveal a sharp and well defined superconducting transition TSC =
0.70 ± 0.07 K. The low-temperature heat capacity measurements show LaRh2Sn2 to be a weakly
coupled  bulk BCS superconductor that has an s-wave singlet ground state with an isotropic energy gap 3.38 ± 0.06 meV. From the field dependence
of the electrical resistance the upper critical field was estimated to be 0.127 ± 0.003 T. With
the calculated penetration depth and coherence length LaRh2Sn2 is a type-II superconductor which was confirmed with low temperature magnetization measurements.
