The material described by CoNi3Si4 crystallizes in the monoclinic Pm space group. Co(1) is bonded in a 10-coordinate geometry to two equivalent Ni(1), two equivalent Ni(2), one Si(1), one Si(2), two equivalent Si(3), and two equivalent Si(4) atoms. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 10-coordinate geometry to two equivalent Co(1), two equivalent Ni(3), one Si(1), one Si(2), two equivalent Si(3), and two equivalent Si(4) atoms. In the second Ni site, Ni(2) is bonded in a 10-coordinate geometry to two equivalent Co(1), two equivalent Ni(3), one Si(3), one Si(4), two equivalent Si(1), and two equivalent Si(2) atoms. In the third Ni site, Ni(3) is bonded in a 6-coordinate geometry to two equivalent Ni(1), two equivalent Ni(2), one Si(3), one Si(4), two equivalent Si(1), and two equivalent Si(2) atoms. There are four inequivalent Si sites. In the first Si site, Si(1) is bonded in a 8-coordinate geometry to one Co(1), one Ni(1), two equivalent Ni(2), two equivalent Ni(3), and two equivalent Si(3) atoms. In the second Si site, Si(2) is bonded in a 8-coordinate geometry to one Co(1), one Ni(1), two equivalent Ni(2), two equivalent Ni(3), and two equivalent Si(4) atoms. In the third Si site, Si(3) is bonded in a 8-coordinate geometry to two equivalent Co(1), one Ni(2), one Ni(3), two equivalent Ni(1), and two equivalent Si(1) atoms. In the fourth Si site, Si(4) is bonded in a 8-coordinate geometry to two equivalent Co(1), one Ni(2), one Ni(3), two equivalent Ni(1), and two equivalent Si(2) atoms. is represented by the CIF card [CIF]
