The compound was found to crystallize in the orthorhombic La3Co2Sn7 structure type (space group Cmmm, no. 65) with lattice parameters: a = 4.556(8) Å, b = 27.345(5) Å and c = 4.562(3) Å. Analysis of the physical properties suggests that only two of three atoms in the formula unit possess localized magnetic moments, which order antiferromagnetically at 4.6 K with some field-induced spin-reorientation in the ordered region. Moreover, Ce3Co2Sn7 exhibits some features of dense Kondo systems with the characteristic Kondo temperature of about 1.2 K. %G English %2 https://univ-rennes.hal.science/hal-01515159/document %2 https://univ-rennes.hal.science/hal-01515159/file/Chajewski%20et%20al.%20-%20Magnetic%20and%20related%20properties%20of%20a%20novel%20compoun.pdf %L hal-01515159 %U https://univ-rennes.hal.science/hal-01515159 %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-RENNES %~ ISCR %~ ISCR-CSM %~ STATS-UR1 %~ UR1-SPM %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ UR1-SDLM %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ TEST-HALCNRS %~ UR1-MMS %~ TEST2-HALCNRS %~ TEST3-HALCNRS
