Materials Data on HW2C9NO10 by Materials Project
W2HW2H(NO)2(CO)18 crystallizes in the monoclinic C2 space group. The structure is zero-dimensional and consists of thirty-six formaldehyde molecules, two W2H clusters, and two W2H(NO)2 clusters. In each W2H cluster, W5+ is bonded in a single-bond geometry to one H1+ atom. The W–H bond length is 1.92 Å. H1+ is bonded in a bent 120 degrees geometry to two equivalent W5+ atoms. In each W2H(NO)2 cluster, W5+ is bonded in a linear geometry to one N3- and one H1+ atom. The W–N bond length is 1.90 Å. The W–H bond length is 1.95 Å. N3- is bonded in a linear geometry to one W5+ and one O2- atom. The N–O bond length is 1.17 Å. H1+ is bonded in a bent 120 degrees geometry to two equivalent W5+ atoms. O2- is bonded in a single-bond geometry to one N3- atom.
