“…1. It is shown that N1, C1, C2, N3 and C15 are nearly located in one plane and the N1-C1, C1-C2, C2-N3, N3-C15 and C15-N1 bond lengths and the corresponding bond angles (Table 4) in the ring are comparable to those in the imidazole ring reported [23][24][25][26]. This confirms the existence of the imidazole ring in compound L 2 .…”

“…A mixture of S-carboxymethyl-N-p-tosyl-l-cysteine (0.0667 g, 0.2 mmol), prepared according to the literature method of Chen et al (2009), 4,4 0 -bipyridine (0.0312 g, 0.2 mmol), Mn(CH 3 COO) 2 Á4H 2 O (0.0490 g, 0.2 mmol) and water (8 ml) was sealed in a 23 ml Teflonlined autoclave, heated at 353 K for 6 d and cooled over a period of 48 h. Yellow crystals of (I) were collected in a yield of 63% (0.0706 g). H atoms of amine groups and water molecules were located in a difference Fourier map and allowed for as riding on their parent atoms [U iso (H) = 1.5U eq (O) and 1.2U eq (N)].…”

In the chiral polymeric title compound, poly[aqua(4,4'-bipyridine)[mu(3)-S-carboxylatomethyl-N-(p-tosyl)-L-cysteinato]manganese(II)], [Mn(C(12)H(13)NO(6)S(2))(C(10)H(8)N(2))(H(2)O)](n), the Mn(II) ion is coordinated in a distorted octahedral geometry by one water molecule, three carboxylate O atoms from three S-carboxyatomethyl-N-(p-tosyl)-L-cysteinate (Ts-cmc) ligands and two N atoms from two 4,4'-bipyridine molecules. Each Ts-cmc ligand behaves as a chiral mu(3)-linker connecting three Mn(II) ions. The two-dimensional frameworks thus formed are further connected by 4,4'-bipyridine ligands into a three-dimensional homochiral metal-organic framework. This is a rare case of a homochiral metal-organic framework with a flexible chiral ligand as linker, and this result demonstrates the important role of noncovalent interactions in stabilizing such assemblies.

“…Because Sr II , Zn II , and Cd II ions are difficult to oxidize or to reduce due to their features of electronic configuration, the emission bands of complexes 1-3 are neither metal-to-ligand charge transfer nor ligand-to-metal charge transfer in nature. [40][41][42][43] So, the emission of 1-3 may be attributed to the ligand-to-ligand charge transfer. The different emission bands of the three polymers may be attributed to the coordination diversities of the metal centres and the rigid differences of coordination modes.…”

Three coordination polymers [Sr(p-H2MOPhIDC)2]n (1) (p-H3MOPhIDC = 2-p-methoxyphenyl-1H-imidazole-4,5-dicarboxylic acid), {[Cd2(p-HMOPhIDC)2(4,4′-bipy)]⋅H2O}n (4,4′-bipy = 4,4′-bipyridine) (2), and [Zn(p-HMOPhIDC)(4,4′-bipy)]n (3) have been solvothermally synthesized, and structurally characterized by single-crystal X-ray diffraction. Polymer 1 indicates a three-dimensional framework, which can be simplified as a 6-connected lattice. Polymer 2 is also a three-dimensional framework, and contains mixed bridging ligands HMOPhIDC2– and 4,4′-bipy. Polymer 3 exhibits a sheet structure bearing infinite rectangles. The coordination modes of the p-H3MOPhIDC ligand, and the thermal and solid-state photoluminescence properties of the polymers have been investigated as well.
