The reaction of aqueous solutions of amino-guanidine hydrogennitrate and acetyl-acetone produces the title pyrazole salt, C(7)H(18)N(8) (2+)·2NO(3) (-). The crystal structure is stabilized by a complex N-H⋯O hydrogen-bonding network. The difference in the engagement of the two nitrate anions in hydrogen bonding is reflected in the variation of the(More)
In the title compound, C(16)H(16)Cl(4)N(3)O(2)P, the phosphoryl and carbonyl groups are anti to each other. The dihedral angle between the benzene rings is 33.59 (16)°. In the crystal, adjacent mol-ecules are linked via N-H⋯O=P and N-H⋯O=C hydrogen bonds, into an extended chain running parallel to the a axis.
