The title compound, C15H15NO3, derived from the condensation of dehydroacetic acid and p-toluidine, crystallizes in a zwitterionic form with cationic iminium and anionic enolate groups, which complete a six-membered pseudocycle via an intramolecular N—H...O hydrogen bond. C—H...O interactions link the molecules into a two-dimensional network.

Ring Motif

In the title compound, C23H15BrO3, the anthracene ring system is essentially planar [maximum deviation = 0.29 (2) Å] and makes a dihedral angle of 5.74 (8)° with the mean plane of the bromo-substituted benzene ring. An intramolecular C—H...O hydrogen bond generates an S(9) ring motif. In the crystal, molecules are linked by C—H...O interactions, forming a two-dimensional network parallel to the ac plane. π–π stacking interactions are observed between benzene rings [centroid–centroid distances = 3.5949 (14) and 3.5960 (13) Å].

Square Pyramidal Geometry

In the title compound, [Cu2(C7H4O5S)2(C12H8N2)2(H2O)2]·3H2O, each copper(II) atom is coordinated by two N atoms from one 1,10-phenanthroline molecule, two carboxylate O atoms from two 2-sulfonatobenzoato dianions and one aqua O atom in a distorted square pyramidal geometry. The 2-sulfonatobenzoato dianions function as μ2-bridging ligands in the formation of a dinuclear complex. Intermolecular hydrogen-bond interactions link the dinuclear units into a two-dimensional network structure.

A cobalt(III)–manganese(II) heterometallic dinuclear complex, [MnII{CoIII(µ-Himn)3}Cl2(CH3OH)], was prepared by a metalloligand approach. X-ray crystallographic analysis indicated that the metalloligand [CoIII(Himn)3] underwent mer/fac geometrical isomerization upon coordination to a Mn ion. Owing to the non-coordinating N–H bonds in the [CoIII(Himn)3] moiety, the heterodinuclear complex exhibited hydrogen bond interactions with the Cl− ligand of the neighboring complex to construct two-dimensional hydrogen-bond networks. The bond distances around the Mn center and the χMT value at 300 K indicate that the Mn center is in a divalent state. The temperature dependence of the χMT product and field dependence of the magnetization showed the isotropic nature of the MnII center.

The Stability

The structure of the title polymeric compound, [Cd(SCN)2(C6H8N2)2]n, exhibits a two-dimensional staircase-like structure parallel to (010) in which the CdIIatom lies on a twofold rotation axis and has a distorted octahedral CdS2N4geometry involving four μ-1,3-(SCN) group donors and two N-atom donors from 1,3-phenylenediamine ligands, which also have twofold symmetry. The major contributions to the cohesion and the stability of this two-dimensional polymeric structure are the covalent Cd—S,N bonds and one weak intralayer N—H...S hydrogen bond.
