The structural, magnetic and electronic properties of the Ruddlesden-Popper material Sr{sub 3}CoRuO{sub 7} have been investigated. Examination of the dc and ac magnetic susceptibility demonstrates that Sr{sub 3}CoRuO{sub 7} exhibits a spin glass transition at 40 K and a magnetic transition at 140 K. Variable-temperature neutron powder diffraction experiments showed no evidence of magnetic diffraction peaks down to 5 K. This suggests the transition at 140 K is a result of short range magnetic order or magnetic clustering of the Co/Ru spins. Sr{sub 3}CoRuO{sub 7} is semiconducting and Mott variable range hopping behaviour is observed below 240 K. - Graphical abstract: Short range antiferromagnetic order is observed below ∼ 140 K in Sr{sub 3}CoRuO{sub 7} followed by spin glass behaviour at 40 K. Display Omitted.
