Re Re Sn Mo
MoRe2Sn crystallizes in the monoclinic Cm space group. Mo(1) is bonded in a 5-coordinate geometry to four equivalent Re(2) and one Sn(1) atom. There are a spread of Mo(1)-Re(2) bond distances ranging from 1.86-2.66 Å. The Mo(1)-Sn(1) bond length is 1.62 Å. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 4-coordinate geometry to one Re(2) and three equivalent Sn(1) atoms. The Re(1)-Re(2) bond length is 2.77 Å. There is one shorter (2.62 Å) and two longer (2.95 Å) Re(1)-Sn(1) bond lengths. In the second Re site, Re(2) is bonded in a 3-coordinate geometry to four equivalent Mo(1) and one Re(1) atom. Sn(1) is bonded in a single-bond geometry to one Mo(1) and three equivalent Re(1) atoms.
