A heterocycle, previously untested as a polydentate ligand, 2,5-bis(2-pyridyl)-1,3,4-thiadiazole, namely bptd, has been found to form the monomeric complexes, Co(bptd) 2(H 2O) 2(NO 3) 2 ( I), Ni(bptd) 2(H 2O) 2(ClO 4) 2 ( II), Co(bptd) 2(H 2O) 2(ClO 4) 2...
(II) atom is five-coordinated in a rather distorted trigonal bipyramidal geometry (tau value=0 537) The Cu-S distances range from 2 3491(4) to 2 4829(4) angstrom, and the Cu-N distances are 1 9987(12) and 2 0584(11) angstrom, respectively An interesting feature of this adduct ...
The most common oxidation number is {eq}Ni^{2+}{/eq}. In this state, nickel can react to form compounds with many anions such as sulfide, sulfate, hydroxides as well as others. Copper(II) nitrate is a blue crystalline solid that is ...
