The two new ozonide compounds K([12]crown-4)2O3 ・ 1.5 NH3 (1) and Rb([12]crown-4)2O3 ・ 1.5 NH3 (2) were synthesized from the binary alkali metal ozonides and [12]crown-4 in liquid ammonia. The air- and temperature-sensitive red, needle-shaped compounds crystallize isostructurally in the non-centrosymmetric space group Fdd2 (no. 43) with 16 formula units per unit cell. The lattice parameters are a = 26.917(8), b = 43.25(1), c = 7.823(2) Å, V = 9108(5) Å3; and a = 26.730(6), b = 44.70(1), c = 7.739(2) Å, V = 9245(4) Å3 for 1 and 2, respectively. The structure comprises rod-like [([M([12]crown-4)2(NH3)]O3)2(NH3)] supramolecular units, forming a fishbone pattern parallel to (001). The ozonide anions are separated from the metal cations and interact only weakly with two ammonia molecules via N-H・ ・ ・O hydrogen bonds

Abstract The title compound has been prepared by the reaction of N-trimethylsilyl-iminotriphenylphos-phorane with copper(II) chloride in boiling CCl4 /C2H5OH, and forms moisture sensitive crystals, which are green in transmittance and black in reflexion. [Me3SiNPPh3 · CuCl2 ] 2 was characterized by its IR spectrum as well as by a crystal structure determination (4197 observed, independent reflexions, R = 0.049). The lattice dimensions are at 20 °C: a = 1102.7. b = 1407.3. c = 1560.2 pm; β = 94.27°; space group P21/n with two formula units in the unit cell. The complex consists of centrosymmetric, dimeric molecules with a planar Cu2 Cl2 ring (Cu-CI bond lengths 229 and 231 pm). A terminally bonded CI atom (Cu-CI = 221 pm) and the N atom of the Me3SiNPPh3 ligand (Cu-N = 198.5 pm) complete the coordination number four of the nearly planar surroundings of the Cu atoms.

The unit cell of N-tert-butyl-3-(tert-butylimino)-2-nitropropen-1-amine (4) is monoclinic, space group P21/C, with a = 9.669(4), b = 16.415(6), c = 17.341 (7) Å, and Z = 4. Hydrolysis of 4 leads to (E)-3-(N-tert-butylamino)-2-nitro-2-propenal (5), whose unit cell is monoclinic, space group P21/n, with a = 6.821(1), b = 20.707(6), c = 6.303(1)Å, and Z = 4. Compounds 4 and 5 both possess C2 symmetry in the solid state, their “U-shaped” conjugated cores being essentially planar. In each case this planarity is enforced by an intramolecular hydrogen bond.
