چکیده
In the crystal structure of the title co-crystal, C(11)H(12)N(3)O(+)·ClO(4) (-)·C(11)H(11)N(3)O, the perchlorate ion is disordered about a twofold rotation axis with the Cl atom located on the twofold rotation axis; the 2-[(2-hy-droxy-benz-yl)amino]-pyrazinium cation and the neutral 2-[(pyrazin-2-yl-amino)-meth-yl]phenol mol-ecule are disordered about the rotation axis in a 1:1 ratio. These two are connected by a pyrazine-pyrazine N(1)-H⋯N(4) hydrogen bond. The cation, whose two aromatic rings are twisted along the -CH(2)-NH- bond by 76.8 (1)°, is a hydrogen-bond donor to the perchlorate ion through the N atom of this link.

In the title compound, C(11)H(11)N(3)O, the aromatic rings at either ends of the -CH(2)-NH- link are twisted by 72.58 (8)°; the hy-droxy substituent is a hydrogen-bond donor to an N atom of the pyrimidine ring. The other N atom of the pyrimidine ring is a hydrogen-bond acceptor to the amino group of an inversion-related mol-ecule.

The binuclear title complex, [Zn2(C33H33N6O)(CH3COO2)(CH3OH)](ClO4)2, was synthesized by the reaction between 2,6-bis-({[bis-(pyridin-2-yl)meth-yl]amino}-meth-yl)-4-methyl-phenol (H-BPMP), Zn(OAc)2 and NaClO4. The two Zn(II) ions are bridged by the phenolate O atom of the octadentate ligand and the acetate group. An additional methanol ligand is terminally coordinated to one of the Zn(II) ions,...

In the title solvate, C(24)H(24)N(2)O(4)·CH(3)NO(2), the benzene ring of the 2-eth-oxy-6-methyl-phenol substituent is approximately perpendicular to the nearly planar benzimidazole ring [maximum deviation = 0.021 (2) Å], making a dihedral angle of 84.32 (7)°. The benzene ring of the 2-eth-oxy-phenol group is somewhat inclined to the benzimidazole ring plane by 28.03 (5)°. The dihedral angle bet...

The non-symmetric title mol-ecule, C32H34N2O5, is based on a tetra-substituted ethyl-enedi-amine backbone. The mol-ecular structure consists of three hy-droxy-benzyl groups and one 2-hy-droxy-5-methyl-benzaldehyde group bonded to the N atoms of the di-amine unit. The ethyl-enedi-amine skeleton shows a regular extended conformation, while the spatial orientation of the phenol arms is governed by...

The title compound, C26H40N2O2, has both its N atoms in trigonal-pyramidal geometries. The mol-ecular structure is stabilized by O-H⋯N and C-H⋯O hydrogen bonds. In the crystal, C-H⋯π inter-actions lead to the formation of a supramolecular helical chain along the b-axis direction.
