Materials Data on CuH14C4(NO2)4 by Materials Project
Cu(HCOO)2(CO(NH2)2)2(H2O)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four hydrazinocarbinol molecules; four water molecules; and one Cu(HCOO)2 sheet oriented in the (0, 0, 1) direction. In the Cu(HCOO)2 sheet, Cu2+ is bonded in a distorted square co-planar geometry to four O2- atoms. There is two shorter (1.98 Å) and two longer (2.00 Å) Cu–O bond length. C3+ is bonded in a trigonal planar geometry to one H1+ and two O2- atoms. The C–H bond length is 1.10 Å. There is one shorter (1.27 Å) and one longer (1.28 Å) C–O bond length. H1+ is bonded in a single-bond geometry to one C3+ atom. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cu2+ and one C3+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cu2+ and one C3+ atom.
