Abstract

ReNSF(CO)5AsF6 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is zero-dimensional and consists of twenty formaldehyde molecules, four AsF6 clusters, and four ReNSF clusters. In each AsF6 cluster, As3- is bonded in an octahedral geometry to six F1- atoms. There is four shorter (1.77 Å) and two longer (1.78 Å) As–F bond length. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one As3- atom. In the second F1- site, F1- is bonded in a single-bond geometry to one As3- atom. In the third F1- site, F1- is bonded in a single-bond geometry to one As3- atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one As3- atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one As3- atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one As3- atom. In each ReNSF cluster, Re5+ is bonded in a single-bond geometry to one N3- atom. The Re–N bond length is 2.07 Å. N3- is bonded in a distorted bent 150 degrees geometry to one Re5+ and one S2- atom. The N–S bond length is 1.44 Å. S2- is bonded in a distorted bent 120 degrees geometry to one N3- and one F1- atom. The S–F bond length is 1.69 Å. F1- is bonded in a single-bond geometry to one S2- atom.
