The compound described by EuNi7In6 is Bergman Structure: Mg32(Al,Zn)49 Bergman-like structured and crystallizes in the orthorhombic Ibam space group. Eu(1) is bonded in a 16-coordinate geometry to four equivalent Ni(2), four equivalent In(1), and eight equivalent In(2) atoms. There are three inequivalent Ni sites. In the first Ni site, Ni(2) is bonded in a 11-coordinate geometry to one Eu(1), one Ni(1), one Ni(3), three equivalent Ni(2), one In(1), and four equivalent In(2) atoms. In the second Ni site, Ni(3) is bonded in a cuboctahedral geometry to two equivalent Ni(1), four equivalent Ni(2), two equivalent In(1), and four equivalent In(2) atoms. In the third Ni site, Ni(1) is bonded in a 10-coordinate geometry to one Ni(3), two equivalent Ni(2), three equivalent In(1), and four equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 13-coordinate geometry to two equivalent Eu(1), one Ni(3), two equivalent Ni(2), three equivalent Ni(1), one In(1), and four equivalent In(2) atoms. In the second In site, In(2) is bonded in a 6-coordinate geometry to two equivalent Eu(1), one Ni(3), two equivalent Ni(1), four equivalent Ni(2), and two equivalent In(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
