Two Molecular Tapes Consisting of Serial or Parallel Azido‐Bridged Eight‐Membered Copper Rings

Synthesis, structure and luminescence of a new series of rigid–flexible lanthanide coordination polymers constructed from benzene sulfonic acid and glutaric acid

“…Herein we have done our endeavor to search for the optimistic reaction conditions in which the two distinct ligands are able to combine together to lanthanide ion at the same time. We have tried to prepare the Ln-BSA-glu system compounds adopting the 1 M L À1 potassium hydroxide liquid as template to adjust the pH value to weak acid (3)(4). And the finally reaction solution was placed at room temperature after 2 weeks, the expected Ln-BSA-glu crystals with well formed and desired yield were obtained.…”

“…A great deal endeavor has been made to design and construction of functional peculiarity lanthanide MOFs because they exhibit attractive and promising applications in the fields of catalysis, luminescence, magnetism, gas adsorption, sensors, and nonlinear optics (NLO), etc. [1][2][3][4][5][6][7][8]. Encouraged by such engaging application prospects, remarkable accomplishments for creation of desired networks and useful functionalizable MOFs materials have been achieved by pioneers [9][10][11][12][13][14].…”

A two-dimensional copper polymer constructed from rod-shaped ferromagnetic secondary building units

“…The Cu2 is four-coordination described as distorted square planar. The basal Cu-N bond lengths are in the range of 1.972-2.005 Å which is identical to Cu-azide compounds [32][33][34][35], and the apical Cu-N bond lengths is 2.442 (3) (Fig. 2).…”

Two chain complexes of [(CH3)2NH2] [M(N3)2(HCOO)] (M=Fe and Co) studied by first-principle electronic-structure calculation

“…The complexes that contain azido or formato ions as versatile bridging ligands and effective magnetic coupling mediators have been widely synthesized and investigated [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Three main modes can be encountered when it is bridging: through two terminal nitrogen atoms in end-to-end (EE) fashion, either in symmetrical or in asymmetrical fashion, or through only one type of the terminal nitrogen atoms in end-on (EO) fashion (Scheme 1).…”
