“…Two phen ligands chelating the central Zn atom form V-shaped cleft and the mono-chelating pimelato ligand is twisted at the carbon atom next to the chelating carboxylato end to adopt a gauche conformation around the C26-C27 bond. The present complex looks very like the monovalent [Zn(phen) 2 (C 8 H 13 O 4 )] + complex cation found in the earlier-reported [Zn(phen) 2 (C 8 H 13 O 4 )](NO 3 ).H 2 O, where the Zn atoms are coordinated by two phen ligands and one hydrogen suberate (C 8 H 13 O 4 )anion (Wei et al, 2002).…”

In the crystal structure of the title compound, [Zn(C7H10O4)(C12H8N2)2]·6H2O, the ZnII atom is coordinated by two carboxylate O atoms of a mono-bidentate chelating pimelate anion (pimelic acid is heptanedioic acid) and four N atoms of two phenanthroline ligands, forming a considerably distorted octahedral ZnN4O2 coordination geometry. The complexes are assembled into a three-dimensional network via C—H⋯O, C—H⋯π and π–π interactions. The mean interplanar distance between adjacent phenanthroline ligands is 3.399 (2) Å.

“…The local coordination environment of 3 can be described as a distorted square-pyramidal structure with an index τ parameter of 0.35 (Figure a). Each phen acts as a terminal ligand with typical Zn−N distances of Zn(1)−N(1) = 2.100(6) and Zn(1)−N(2) = 2.108(6) Å and a chelating angle of N(1)−Zn(1)−N(2) = 79.2(2)° . The remaining coordination positions of the metal atom are saturated by the bis-monodentate BM-5-CATP (Zn(1)−O(1) = 2.023(5), Zn(1)−O(3A) = 2.004(6)) and one water molecule (Zn(1)−O(5) = 2.087(5)).…”

Photochromism of Novel Metal Coordination Polymers with 1,2-Bis(2‘-methyl-5‘-(carboxylic acid)-3‘-thienyl)perfluorocyclopentene in the Crystalline Phase

et al. 2007

Three new metal complexes with 1,2-bis(2'-methyl-5'-(carboxylic acid)-3'-thienyl)perfluorocyclopentene (BM-5-CATP) were synthesized and characterized by X-ray diffraction analysis. BM-5-CATP serves as a bis-monodentate ligand that bridges metal centers to generate three 1D polymers. The two thienyl rings in the three complexes adopt antiparallel fashions, and the distances of 3.39, 3.53, and 3.57 A between the two reactive carbons are short enough to allow photocyclizations to occur in the crystalline phase. [Co(BM-5-CATP)(py)2(MeOH)2] (1) displayed effective photoisomerization in the crystalline phase. Interestingly, solvated 1 underwent a solid-state conversion upon heating to generate, through the release of the coordinated MeOH and rearrangement of the coordination geometry, the desolvated form (1a), while maintaining reversible photochromism. The removal of the solvent led to obvious changes in physical properties such as color and magnetic properties. The ESR spectra of 1 and 1a changed reversibly upon photoexcitation, indicating changes in coordination geometry accompanied by photoreaction. The magnetic susceptibilities of 1 and 1a showed no obvious changes, suggesting that the cobalt-cobalt interaction through the long bridging BM-5-CATP is less effective. Both [Cu(BM-5-CATP)(py)3](EtOH)(py)1.8 (2) and [Zn(BM-5-CATP)(phen)(H2O)] (3) exhibited reversible photoreactions in the crystalline phase. However, 3 did not show remarkable spectral changes because of steric hindrance from the coordinated bulky phenanthroline and the intramolecular H bonds.

In the title compound, [Zn(C7H4BrO2)(C12H8N2)2(H2O)](C7H4BrO2)·1.5H2O, the ZnII atom is coordinated by four N atoms from two chelating 1,10-phenanthroline (phen) ligands, one O atom from a 4-bromobenzoate ligand and one water molecule, completing a distorted ZnN4O2 octahedral geometry. The two phen ligands exhibit nearly perfect coplanarity (r.m.s. deviations = 0.027 and 0.031 Å), making a dihedral angle of 85.7 (1)°. The mean interplanar distances of 3.36 (2) and 3.41 (3) Å between adjacent phen ligands indicate π–π stacking interactions. The uncoordinated water molecules are partly occupied. One carboxylate O atom and two Br atoms are each disordered over two sites, with occupancy factors of 0.60 and 0.40. In the crystal structure, O—H⋯O and C—H⋯O hydrogen bonds and π–π stacking interactions link the complex cations, uncoordinated 4-bromobenzoate anions and water molecules into a three-dimensional supramolecular network. An intramolecular O—H⋯·O hydrogen bond is observed in the cation.
