We report on the structure and physical properties of a bidimensional chromate, Sr 4 Cr 3 O 10 , the n=3 member of the Ruddlesden-Popper Sr n+1 Cr n O 3n+1 series. For the first time, using complementary x-ray powder diffraction and electron diffraction data, we have solved its layered crystallographic structure. Our study shows also that this high pressure phase is insulating and antiferromagnetic below T N =280K, a similar behavior already observed for n=1, 2 and n=+∞ members.
