compound [Cu8(tpbpa)(μ-CN)8]n·2nH2O (7) exhibits a three-dimensional (3D) frameworkcontaining a ⋯PM⋯ double helical structure, although both of them contain (CuCN)n chains. The compound [Cu2(tdpa)(μ-I)2]n (8) is a zig-zag chainbased on the star-shaped molecule tpda, in which one of three dpa-arms is free of coordination to metalions. All complexes exhibit luminescence in the solid state.

The ligand tppda has been designed and synthesized as molecular leverage for helicity control when reacted with Cd2+ ions. The guests MeOH or DMF preferentially stabilize the P-helical isomer, while the guest H2O causes a helix inversion to give the M-helical isomer as the major isomer without any chiral auxiliary.

Two Cd(II)-tppda (tppda = N,N,N',N'-tetrakis(2-pyridyl)-2,6-pyridinediamine) coordination polymers have been prepared via variations of the templating solvent. The solvated complex [Cd-2(tppda)(DMF)(2)(mu-SCN)(2)(SCN)(2)](n) (1) exhibits a 1-D pseudo-helical structure, whereas the unsolvated complex [Cd-2(tppda)(mu-SCN)(4)](n) (2) features a 2-D metal-organic framework (MOF). Both are luminescent in the solid state, with emission maxima 444 and 435 nm for 1 and 2, respectively. (c) 2006 Elsevier B.V. All rights reserved.

Electrocatalytic CO2 reduction to C2 products is a promising technique when compared with the traditionally complicated and energy intensive routes in the industrial process. As an important bulk chemical, it is highly desirable for acetic acid to be produced via a sustainable method. In this work, we prepared N-based Cu(I)/C-doped boron nitride (BN-C) composites for electrocatalytic reduction of CO2 to acetic
