The structure described by Ca3(InN2)2 crystallizes in the orthorhombic Pnna space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a 5-coordinate geometry to two equivalent N(1) and three equivalent N(2) atoms. In the second Ca site, Ca(2) is bonded in a 6-coordinate geometry to two equivalent N(2) and four equivalent N(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted edge-sharing InN4 tetrahedra. In the second In site, In(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted edge-sharing InN4 trigonal pyramids. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Ca(1), two equivalent Ca(2), one In(1), and one In(2) atom to form a mixture of distorted edge, corner, and face-sharing NCa4In2 pentagonal pyramids. In the second N site, N(2) is bonded in a 6-coordinate geometry to one Ca(2), three equivalent Ca(1), one In(1), and one In(2) atom. is represented by the CIF card [CIF]
