We report a coexistence of superconductivity and antiferromagnetism in HgBa2Ca4Cu5Oy with Tc = 108 K trough Cu-NMR measurements. This compound is composed of two kinds of CuO2 planes in a unit cell, three inner planes (IP) and two outer planes (OP). The OP is optimally-doped, undergoing a superconducting transition at Tc = 108 K, whereas the IP is strongly underdoped, doing an antiferromagnetic transition below TN ∼ 60 K.
