متن کامل(S)-2-Amino-1-(pyrrolidinium-2-ylmethyl)pyridinium dibromide
In the title compound, C(10)H(17)N(3) (2+)·2Br(-), the pyrrolidinium ring displays an envelope conformation, with the flap N atom lying 0.564 (6) Å from the mean plane of the remaining four C atoms. The attached methyl-ene C atom, which connects the pyrrolidinium ring and the 2-amino-pyridine group, is displaced from the plane of the four pyrrolidinium C atoms by 0.811 (8) Å in the same directi...
متن کامل{(S)-2-[({2-[1-(Anthracen-9-ylmethyl)pyrrolidine-2-carboxamido]phenyl}(phenyl)methylidene)amino]acetato(2−)-κ4 N,N′,N′′,O 1}nickel(II)
The title compound, [Ni(C(35)H(29)N(3)O(3))], includes a Schiff base ligand derived from (S)-1-[(anthracen-9-yl)meth-yl]-N-(2-benz-oyl-phen-yl)pyrrolidine-2-carboxamide and glycine. The Ni(II) atom is coordinated by three N atoms [Ni-N = 1.937 (3), 1.850 (3) and 1.850 (3) Å] and one O atom [Ni-O = 1.859 (2) Å], resulting in a pseudo-square-planar coordination environment.

In the zwitterionic title compound, C(16)H(12)N(2)O, the dihedral angle between the benzene ring and naphthalene ring system is 2.0 (1)°. The azo group adopts a trans configuration and an intra-molecular N-H⋯O hydrogen bond is found. In the crystal, the mol-ecules are packed by strong π-π inter-actions [centroid-centroid distance between aromatic rings = 3.375 (3) Å].

In the title structure, C(7)H(9)N(3)O(2)·H(2)O, there are two formula units in the asymmetric unit. The mol-ecule is a zwitterion, containing a quaternary N atom and a deprotonated carboxyl group, with C-O distances in the range 1.256 (2)-1.266 (3) Å. The two independent mol-ecules form a hydrogen-bonded R(2) (2)(16) dimer about an approximate inversion center via N-H⋯O hydrogen bonds, with N⋯O...
