THE TITLE COMPOUND (SYSTEMATIC NAME 4-{3-[2-aza-tricyclo-[9.4.0.0(3,8)]penta-deca-1(15),3,5,7,11,13-hexaen-2-yl]prop-yl}-1-(2-hy-droxy-eth-yl)piperazine-1,4-diium dichloride), C(23)H(31)N(3)O(+)·2Cl(-), is the dihydro-chloride of a piperazine derivative bearing a bulky 3-(5H-dibenz[b,f]azepin-5-yl)propyl substituent. Protonation took place on both N atoms of the piperazine unit. The diaza-cyclo...

In the title compound, C(18)H(18)F(2)N(2)O(3)S, the piperazine ring adopts a chair conformation. The dihedral angle between the sulfonyl-bound benzene ring and the best fit plane throught the six non-H atoms of the piperazine ring is 69.4 (2)°, while those between the fluoro-benzene and sulfonyl rings and the fluoro-benzene and piperazine rings are 30.97 (2) and 75.98 (2)°, respectively. In the...

In the title compound, C15H19N3O2, the piperazine ring adopts a chair conformation, with its N-C bonds in pseudo-equatorial orientations. The dihedral angle between the C atoms of the piperazine ring and the phthalamide ring system (r.m.s. deviaiton = 0.008 Å) is 89.30 (8)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, generating a three-dimensional network and aromatic π-π in...

In the crystal structure of the title compound, C(19)H(21)F(3)N(2)O(2)S, the piperazine ring adopts a chair conformation. The dihedral angles between the mean plane of the piperazine ring and the tosyl and trifluoro-methyl-phenyl rings are 74.52 (3) and 68.30 (2)°, respectively. The sulfonamide N atom deviates from the plane defined by the three attached atoms by 0.327 (1) Å. The crystal struct...
