The compound, C(15)H(16)N(2)O(2), features a pyrroline ring fused with a seven-membered diazepine ring; the latter system adopts a boat conformation (with the methine C atom as the prow and the two C atoms of the aromatic ring as the stern). A CH(2)-CH(2) segment of the pyrroline ring is disordered over two positions in a 1:1 ratio.

The title compound, C(26)H(22)N(2)O(2), features a benzene ring fused with a seven-membered diazepine ring; the latter ring adopts a boat conformation (with the propargylallyl-bearing C atom as the prow and the fused-ring C atoms as the stern). The phenyl ring of one of the two benzyl substituents is disordered over two positions in a 0.812 (11):0.188 (11) ratio.

The title compound, C12H18N2·0.5H2O, crystallizes with two independent organic mol-ecules (A and B) in the asymmetric unit, together with a water mol-ecule of crystallization. The diazepine rings in each mol-ecule have a chair conformation. The dihedral angle between benzene ring and the mean plane of the diazepine ring is 21.15 (12)° in mol-ecule A and 17.42 (11)° in mol-ecule B. In the crysta...

In the title compound, C(27)H(23)Cl(3)N(4)O(2), the seven-membered diazepine ring adopts a boat conformation. The triazole ring makes dihedral angles of 17.24 (8) and 82.86 (8)°, respectively, with the chloro-benzene ring and the benzene ring of the benzodiazepine unit.

The X-ray structure of the title compound has been determined for first time. Data on its 1H–13C-NMR coupling constants and 15N-NMR spectrum are also given.

The 6-amino-6-methyl-1,4-diazepine framework is a readily available neutral 6-electron ligand moiety, suitable to support cationic group 3 metal alkyl catalysts; it also provides convenient access to tri- and tetradentate monoanionic ligand derivatives.

In the title compound, C(25)H(23)N(3)O(3), the seven-membered diazepine ring adopts a boat conformation with the hydroxy-substituted C atom at the prow and fused-ring C atoms at the stern. The crystal packing features C-H⋯O, C-H⋯π and N-H ⋯π inter-actions.

The asymmetric unit of the title compound, C(18)H(18)N(2)O(2), contains three independent mol-ecules. In each, the seven-membered diazepine ring adopts a boat conformation with the hy-droxy-substituted C atom at the prow and fused-ring C atoms at the stern. In the crystal, the mol-ecules are linked by O-H⋯O and N-H⋯O hydrogen bonds. The allyl group of one mol-ecule is equally disordered over tw...
