PtN2N2(NO3)2 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of sixteen ammonia molecules, eight cis-platinum-(nh3)2 molecules, and sixteen nitric acid molecules.
PtN2ONO3 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one azanide;platinum(2+);dihydrate molecule and two nitric acid molecules.
(PtON1)3N2NONO2(NO3)2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of four ammonia molecules, four nitric acid molecules, two nitrous acid molecules, two nitroxyl molecules, and two PtON1 clusters. In each PtON1 cluster, there are three inequivalent Pt5+ sites. In the first Pt5+ site, Pt5+ is bonded in a 3-coordinate geometry to one N1+ and two O2- atoms. The Pt–N bond length is 1.75 Å. There are one shorter (1.94 Å) and one longer (2.10 Å) Pt–O bond lengths. In the second Pt5+ site, Pt5+ is bonded in a distorted T-shaped geometry to one N1+ and two O2- atoms. The Pt–N bond length is 1.74 Å. There are one shorter (1.89 Å) and one longer (2.14 Å) Pt–O bond lengths. In the third Pt5+ site, Pt5+ is bonded in a T-shaped geometry to one N1+ and two O2- atoms. The Pt–N bond length is 1.72 Å. There is one shorter (1.86 Å) and one longer (2.04 Å) Pt–O bond length. There are three inequivalent N1+ sites. In the first N1+ site, N1+ is bonded in a single-bond geometry to one Pt5+ atom. In the second N1+ site, N1+ is bonded in a single-bond geometry to one Pt5+ atom. In the third N1+ site, N1+ is bonded in a single-bond geometry to one Pt5+ atom. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two Pt5+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two Pt5+ atoms. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Pt5+ atoms.
Pt(NO)2O2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four hydrogen peroxide molecules and four Pt(NO)2 clusters. In each Pt(NO)2 cluster, Pt6+ is bonded in a linear geometry to two equivalent N1+ atoms. Both Pt–N bond lengths are 1.82 Å. N1+ is bonded in a distorted linear geometry to one Pt6+ and one O2- atom. The N–O bond length is 1.18 Å. O2- is bonded in a single-bond geometry to one N1+ atom.
Pt(NO3)2 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of one oxygen molecule and one Pt(NO2)2 ribbon oriented in the (1, 0, 0) direction. In the Pt(NO2)2 ribbon, Pt2+ is bonded to six O2- atoms to form edge-sharing PtO6 octahedra. There are four shorter (2.00 Å) and two longer (2.06 Å) Pt–O bond lengths. N5+ is bonded in a single-bond geometry to one O2- atom. The N–O bond length is 1.29 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Pt2+ and one N5+ atom. In the second O2- site, O2- is bonded in a water-like geometry to two equivalent Pt2+ atoms.
Pt(NO3)2 crystallizes in the trigonal R-3 space group. The structure is two-dimensional and consists of three Pt(NO3)2 sheets oriented in the (0, 0, 1) direction. Pt2+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Pt–O bond lengths are 2.15 Å. N5+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All N–O bond lengths are 1.29 Å. O2- is bonded in a bent 120 degrees geometry to one Pt2+ and one N5+ atom.
