By using mixed rigid and flexible organic ligands, three Keggin based compounds, [Ag6(tbz)4(bmz)2(H3PW12O40)]·4H2O (1), [Ag(H2bdpm)2(H2PMo12O40)]·7.5H2O (2), and [Ag4(tbz)2(H2bdpm)2(HPMo12O40)]·2H2O (3) (Htbz = thiabendazole, Hbmz = benzimidazole, H2bdpm = 1,1'-bis(3,5-dimethyl-1H-pyrazolate)methane), were hydrothermally synthesized and structurally characterized. Through adopting rigid Htbz li...

The structure of the title compound, (Ag(0.79)Co(0.11))Co(H(2)O)(2)[BP(2)O(8)]·0.67H(2)O is isotypic to that of its recently published counterparts AgMg(H(2)O)(2)[BP(2)O(8)]·H(2)O and (Ag(0.57)Ni(0.22))Ni(H(2)O)(2)[BP(2)O(8)]·0.67H(2)O. It consists of infinite borophos-phate helical ribbons [BP(2)O(8)](3-), built up from alternate BO(4) and PO(4) tetra-hedra arranged around the 6(5) screw axes....

In the title complex, [Cu(NO(3))(2)(C(17)H(18)FN(3)O(3))(2)], the Cu(II) ion is located on an inversion center. It exhibits a distorted octa-hedral geometry, being coordinated by six O atoms, four from two ciprofloxacin ligand mol-ecules (L), which act as bidentate ligands, and two from two nitrate anions. In the ligand, the piperazine ring has a chair conformation and the quinoline system is e...

Within the scope of this paper, nine π-expanded mono-substituted 5,8,11,14,17-pentakis-(tert-butyl)-hexa-peri-hexabenzocoronenes (HBC) are introduced. 2-Iodo-5,8,11,14,17-pentakis-(tert-butyl)-hexa-peri-hexabenzocoronene served as precursor and was reacted with ethynyltrimethylsilane in a Sonogashira coupling reaction. The acetylene unit is used linker can undergo another reaction combining dif...

The genus Achillea L. includes more than 100 species and is a polyploid complex of di-, tetra-, hexa- and octaploids, individuals.
