Sr Mn Mn Ag
SrMn2Ag crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a distorted single-bond geometry to one Mn(1) and one Mn(2) atom. The Sr(1)-Mn(1) bond length is 0.50 Å. The Sr(1)-Mn(2) bond length is 2.00 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a single-bond geometry to one Sr(1) and one Ag(1) atom. The Mn(1)-Ag(1) bond length is 3.70 Å. In the second Mn site, Mn(2) is bonded in a single-bond geometry to one Sr(1) and one Ag(1) atom. The Mn(2)-Ag(1) bond length is 3.70 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to one Mn(1); one Mn(2); and six Ag(1,1) atoms to form a mixture of distorted edge and corner-sharing AgMn2Ag6 hexagonal bipyramids. All Ag(1)-Ag(1,1) bond lengths are 3.27 Å. In the second Ag site, Ag(1) is bonded to one Mn(1); one Mn(2); and six Ag(1,1) atoms to form a mixture of distorted edge and corner-sharing AgMn2Ag6 hexagonal bipyramids. The Ag(1)-Mn(1) bond length is 3.70 Å. The Ag(1)-Mn(2) bond length is 3.70 Å. Both Ag(1)-Ag(1) bond lengths are 3.27 Å.
