3-Phenyl-N,N,N′,N′-tetra­methyl-1-ethyne-1-carboximidamidium bromide

The reaction of 3,3,3-tris-(dimethyl-amino)-1-phenyl-prop-1-yne with bromine in pentane yields the title compound, C(13)H(17)N(2) (+)·Br(-). The acetyl-enic bond distance [1.197 (2) Å] is consistent with a C C triple bond. The amidinium C=N bonds [1.325 (2) and 1.330 (2) Å] have double-bond character and the positive charge is delocalized between the two dimethyl-amino groups.

3,5-Diamino-1-phenyl-1,2,4-triazolium bromide

The title salt, C(8)H(10)N(5) (+)·Br(-), crystallizes with two independent structural units in the asymmetric unit. The two independent cations have different conformations, the triazole and phenyl rings forming dihedral angles of 32.57 (6) and 52.27 (7)°. In both cations, the amino groups are planar (the sum of the angles at the N atom of each amino group is 360°) and conjugated with the triaz...

The title compound, C(8)H(18)N(4)O(2) (2+)·2Cl(-), contains two oxime groups. The methyl oxime group has a Z configuration, and the ethyl oxime group is disordered, with both Z and E configurations in occupancies of 0.840 (8) and 0.160 (8), respectively. In the crystal structure, there are a number of N-H⋯Cl hydrogen bonds.

In the title compound, C(13)H(23)N(2)O(2) (+)·Br(-), the octyl chain has an all-trans conformation. In the crystal, the cations are linked by C-H⋯O bonds into a zigzag chain along the b axis. The bromide anions further link the chains via C-H⋯Br inter-actions into a two-dimensional array parallel to the ab plane. An O-H⋯Br interaction is also observed.

(1R,3R,3aS,8aR)-4-Oxo-3-phenyl-1-[(1R)-1-phenyl­eth­yl]deca­hydro­cyclo­hepta­[b]pyrrol-1-ium bromide

The title chiral compound, C(23)H(28)NO(+)·Br(-), was obtained from an optically active amino-ethanol precursor. The pyrrolidine heterocycle has an envelope conformation, with the C atom α-positioned with respect to the keto group deviating by 0.570 (6) Å from the mean plane of other atoms. The trans-fused seven-membered ring adopts a pseudo-chair conformation. The two phenyl rings form a dihed...
