Low-temperature redetermination of 4-chloro-2-[tris-(hydroxy-meth-yl)methyl-imino-meth-yl]phenol as zwitterionic 4-chloro-2-[tris-(hydroxy-meth-yl)methyl-iminiometh-yl]phenolate.

ABSTRACT: The title Schiff base, C(11)H(14)ClNO(4), originally refined as a neutral mol-ecule [Chumakov, Antosyak, Mazus, Tsapkov & Samus (2000), Crystallogr. Rep.45, 945-950], is inter-preted as a zwitterionic compound. There are two independent zwitterions in the asymmetric unit. Five of the six hydr-oxy groups of the -CH(2)OH fragments are disordered. In one zwitterion, two are disordered over three sites [0.53?(1):0.33?(1):0.14?(1) and 0.65?(1):0.18?(1):0.17?(1)] and the third over two sites [0.66?(1):0.34?(1)]. In the second zwitterion, two are disordered over two sites [0.84?(1):0.16?(1) and 0.83?(1):0.17?(1)] and the third hydr-oxy group is ordered.

Tris{2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolate-?O,O'}tris-(thio-cyanato-?N)europium(III).

Project description:The metal center in the structure of the title compound, [Eu(NCS)(3)(C(15)H(15)NO(2))(3)], is coordinated by three Schiff base 2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolate (L) ligands and three independent thio-cyanate ions. In the crystal structure, the acidic H atom is located on the Schiff base N atom and hydrogen bonded to the phenolate O atom. The coordination environment of the Eu(III) ion is nine-coordinate by three chelating methoxy-phenolate pairs of O atoms and three N-atom terminals of the thio-cyanate ions. The compound is isostructural with the Ce(III) analogue [Liu et al. (2009 ?). Acta Cryst. E65, m650].

Project description:In the title compound, [La(NCS)(3)(C(15)H(15)NO(2))(3)], the metal centre is nine-coordinated by six O atoms from three zwitterionic Schiff base 2-meth-oxy-6-[(4-methyl-phen-yl)iminio-meth-yl]phenolate (L) ligands and three terminal N atoms of the thio-cyanate ions in a monocapped square-anti-prismatic environment.

Bis[6-meth-oxy-2-[(4-methyl-phen-yl)iminiometh-yl]phenolate-?O]tris-(nitrato-?O,O')ytterbium(III) monohydrate.

Project description:The crystal structure of title compound, [Yb(NO(3))(3)(C(15)H(15)NO(2))(2)]·H(2)O, contains two Schiff base 2-[(4-methyl-phen-yl)imino-meth-yl]-6-methoxy-phenol (HL) ligands, three independent nitrate ions that chelate to the ytterbium(III) ion in an O,O'-bidentate manner and an uncoordinated water mol-ecule. The coordination number of the Yb(III) ion is eight. The HL ligands chelate with a strong Yb-O(phenolate) bond and a weak Yb-O(meth-oxy) contact. The latter augments the coordination polyhedron to give a YbO(10) bicapped square antiprism. Classical inter-molecular O-H?O and N-H?O hydrogen bonds as well as weak C-H?O contacts contribute to the stability of the structure.

(E)-4-Bromo-2-[(2-hydroxy-phen-yl)iminiometh-yl]phenolate.

Project description:The title compound, C(13)H(10)BrNO(2), crystallizes in a zwitterionic form. The zwitterion exists in a trans configuration about the C=N bond and is almost planar, the dihedral angle between the two benzene rings being 2.29?(9)°. An intra-molecular N-H?O hydrogen bond formed between the iminium NH(+) and the phenolate O(-) atoms generates an S(6) ring motif. In the crystal, the zwitterions are linked through O-H?O hydrogen bonds into chains along [101] and these chains are further connected through C-H?Br inter-actions into a two-dimensional network perpendicular to (101). C?C [3.572?(3)-3.592?(3)?Å] and C?Br [3.5633?(19)-3.7339?(18)?Å] short contacts are observed. The crystal studied was a twin with twin law 00, 00, 001 with a domain ratio of 0.09919?(2):0.90081?(2).

2-((E)-{2-[(E)-2,3-Dihydroxy-benzyl-ideneamino]-5-methyl-phen-yl}iminiometh-yl)-6-hydroxy-phenolate.

Project description:The asymmetric unit of the title Schiff base compound, C(21)H(18)N(2)O(4), consists of four independent zwitterions (A, B, C and D) with similar conformations. In each independent mol-ecule, the methyl group is disordered over two positions; the occupancies of the two positions are 0.819 (5) and 0.181 (5) in mol-ecule A, 0.912 (5) and 0.088 (5) in B, 0.734 (5) and 0.266 (5) in C, and 0.940 (6) and 0.060 (6) in D. The dihydroxy-phenyl and the hydroxy-phenolate rings in mol-ecule A form dihedral angles of 17.36 (12) and 13.30 (12)°, respectively, with the central benzene ring, whereas the respective angles for mol-ecules B, C and D are 30.22 (11)/7.46 (11), 35.26 (12)/11.01 (12) and 39.89 (12)/4.29 (12)°. In all independent mol-ecules, intra-molecular N-H⋯O and O-H⋯N hydrogen bonds generate S(6) ring motifs. The four independent mol-ecules are linked into two pairs, viz. A-B and C-D, by inter-molecular O-H⋯O hydrogen bonds. These pairs are linked into a two-dimensional network parallel to the ab plane by C-H⋯O hydrogen bonds. In addition, C-H⋯π and π-π [centroid-centroid distance = 3.5153 (14)-3.7810 (15) Å] inter-actions stabilize the crystal structure.

(E)-4-Allyl-2-[(2-hydroxy-phen-yl)iminiometh-yl]-6-methoxy-phenolate.

Project description:The title compound, C(17)H(17)NO(3), crystallizes in a zwitterionic form with cationic iminium and anionic enolate groups. The zwitterion exists in a trans configuration about the C=N bond. The dihedral angle between the two benzene rings is 13.42 (7)°. The meth-oxy group is almost coplanar [C-O-C-C = 2.1 (2)°] with the attached ring whereas the allyl unit is oriented at a dihedral angle of 67.9 (1)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, the mol-ecules are linked into zigzag chains along [010] by O-H⋯O hydrogen bonds. In addition, weak C-H⋯π inter-actions are observed.

Zwitterionic 4-bromo-6-meth-oxy-2-{[tris-(hy-droxy-meth-yl)methyl]-iminiumyl-meth-yl}phenolate: crystal structure and Hirshfeld surface analysis.

Project description:In the solid state, the title compound, C12H16BrNO5 [systematic name: 4-bromo-2-((1E)-{[1,3-dihy-droxy-2-(hy-droxy-meth-yl)propan-2-yl]iminium-yl}meth-yl)-6-meth-oxy-benzen-1-olate], C12H16BrNO5, is found in the keto-amine tautomeric form, with an intra-molecular iminium-N-H?O(phenolate) hydrogen bond and an E conformation about the C=N bond. Both gauche (two) and anti relationships are found for the methyl-hydroxy groups. In the crystal, a supra-molecular layer in the bc plane is formed via hy-droxy-O-H?O(hy-droxy) and charge-assisted hy-droxy-O-H?O(phenolate) hydrogen-bonding inter-actions; various C-H?O inter-actions provide additional cohesion to the layers, which stack along the a axis with no directional inter-actions between them. A Hirshfeld surface analysis confirms the lack of specific inter-actions in the inter-layer region.
