With solvent molecules participating in coordination systems, four new MnII polymers of the rigid ligand 2,3,5,6-tetrachloro-1,4-benzenedicarboxylic acid (H2BDC-Cl4) have been obtained from different media. Single-crystal X-ray analysis indicates that arrays 1−4 vary 1D fishbone or zigzag chain for 1 2, 2D (4,4) layer 3, to 3D SrAl2 network 4, respectively. In {[Mn(BDC-Cl4)(py)2(H2O)2](py)2}n (1) and {[Mn(BDC-Cl4)(MeOH)3](MeOH)}n (2), pyridine/water (in 1) MeOH 2) act as monodentate terminal...
Entangled nets in coordination compounds with both self-penetrating and interpenetrating structural features have been first constructed by using a flexible bis-pyridinecarboxamide isophthalate or 5-methylisophthalate. Distinct entangled systems showing 3-fold interpenetration polyrotaxane can also be obtained altering the 5-substituents of isophthalate.
A series of novel metal–organic frameworks (MOFs) have been assembled from PbII and 2,3,5,6-tetrachloro-1,4-benzenedicarboxylic acid (H2BDC-Cl4) by simply adding different alkali metal ions as templates. When only lead nitrate is used, a robust 3D open framework [Pb(BDC-Cl4)(MeOH)2]n (1) with pts topology can be obtained. Incorporating the lighter LiI or NaI into above PbII/BDC-Cl4 system results in two unique isostructural PbII–LiI PbII–NaI heterometallic frameworks,...
Abstract A palladium‐catalyzed, one‐pot synthesis of unsymmetrical aryl alkyl thioethers involving halides (aryl bromides and chlorides), thiourea has been realized under mild conditions (room temperature to 50 °C) in water with polyoxyethanyl α‐tocopheryl sebacate (PTS) as amphiphile. The PTS/water could be recycled up eight runs without an obvious change its activity.
Two chiral d10 metallosupramolecular systems based on an achiral fluorinated Schiff-base ligand have been prepared and characterized. The ZnII complex 1 reveals 21 helical coordination chains with the inclusion of rare water opposite helix in perpendicular channels, whereas CdII 2 displays homochiral 1D motifs 31 symmetry a 3D supramolecular architecture built by C–H···F interactions.
Four polymeric d10 metal terephthalate complexes incorporating bis-pyridinecarboxamide building blocks were prepared to explore the effect of central ion or fluorine substituent ligand on topology and entanglement coordination networks. The combination ZnII with a fluorinated leads noninterpenetrated layer honeycomb (hcb) for complex 1. Interestingly, other three materials display unusual entangling For 2, reaction zinc nonfluorinated affords three-dimensional diamond (dia) architecture [3 +...
