Assembly of Trigonal and Tetragonal Prismatic Cages from Octahedral Metal Ions and a Flexible Molecular Clip

Abstract

Reaction of a semirigid ligand with two octahedral metal ions with restricted coordination symmetry afforded metalated container complexes showing trigonal or tetragonal outer shapes and inner cavities.

Synthesis, fluorescence, and sorption properties of cobalt coordination polymers of the N,N′-bis(4-pyridylmethyl)naphthalene diimide ligand

“…2). In contrast, in complexes 2 and 3, the ligand adopts the Zmode, which is more commonly observed [1,[12][13][14][15]. The M 4 L 4 rhombic grid has an average edge length of 15.2 Å , such that another non-coordinated CF 3 SO 3 -ion is encapsulated within the rhombic grid.…”

“…Consequently, it is also important to study the influence of anions on the resulting frameworks of coordination polymers. Our group has been working on the supramolecular synthesis of various coordination polymer assemblies with semirigid ligands containing a freely rotatable methylene (-CH 2 -) connector between a rigid spacer and pyridyl arms, and a great diversity of discrete molecular architectures or infinite coordination polymers has been constructed [12][13][14][15]. However, bis-pyridyl ligands having a backbone capable of hydrogen bonding or pÁÁÁp interactions have not been explored in much detail.…”

“…The title compound have been used for the synthesis of some metal complexes [4,5]. In the title crystal structure one molecule is present in the asymmetric unit.…”

Crystal structure of (1S,2R,6R,7R,8S,12S)-4,10,17-triphenyl-15-thia-4,10-diazapentacyclo[5.5.5.01,16.02,6.08,12]heptadeca-13,16-diene-3,5,9,11-tetronep-xylene hemisolvate

“…8. Fifteen organometallic entries were found, including interpenetrating nets (Zhang et al, 2011), container complexes (Liu et al, 2007), and other multi-metalcenter complexes (Yu et al, 2012;Zhang, 2012). Thirteen organic entries were found, including the aforementioned (7) Twisting of N-phenyl rings (C27 forward, C33 behind) viewed along [514], normal to the thiophene moiety.…”
