One-dimensional coordination polymers generated from a new triazole bridging ligand and HgX2 (X = Cl, Br and I): characterization and luminescent properties
The new 4-amino-1,2,4-triazole asymmetric bridging ligand 4-amino-5-(pyridin-3-yl)-3-[4-(pyridin-4-yl)phenyl]-4H-1,2,4-triazole (L) has been used to generate three novel isomorphic one-dimensional coordination polymers, viz. catena-poly[[tris[dichloridomercury(II)]-bis{μ3-4-amino-5-(pyridin-3-yl)-3-[4-(pyridin-4-yl)phenyl]-4H-1,2,4-triazole}] acetonitrile monosolvate], {[Hg3Cl6(C18H14N6)2]·CH3CN}n, (I), and the bromido, {[Hg3Br6(C18H14N6)2]·CH3CN}n, (II), and iodido, {[Hg3I6(C18H14N6)2]·CH3CN}n, (III), analogs. The asymmetric ligand acts as a tridentate ligand to coordinate the three different HgII centers (two of which are symmetry-related). Two ligands and two symmetry-related HgII centers form centrosymmetric rectangular units which are linked into one-dimensional chains via the oth...

Tight skinny jeans can cause nerve damage, doctor warns
From Kate Moss to Russell Brand skinny jeans are a integral part of any hipster's wardrobe. But fans of tight-hugging denim are putting themselves at risk, according to a doctor from the Greater Baltimore Medical Center. (Source: the Mail online | Health)
