K Mn Mn In In
K(MnIn)2 crystallizes in the monoclinic Cm space group. K(1) is bonded in a single-bond geometry to one Mn(1) and two equivalent In(1) atoms. The K(1)-Mn(1) bond length is 0.17 Å. Both K(1)-In(1) bond lengths are 3.83 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a single-bond geometry to one K(1) and one Mn(2) atom. The Mn(1)-Mn(2) bond length is 1.41 Å. In the second Mn site, Mn(2) is bonded to one Mn(1) and four equivalent In(1) atoms to form distorted corner-sharing MnMnIn4 trigonal bipyramids. There are two shorter (2.57 Å) and two longer (2.61 Å) Mn(2)-In(1) bond lengths. In(1) is bonded in a 3-coordinate geometry to one K(1) and two equivalent Mn(2) atoms.
