The crystal structure of a complex of cupric chloride and 1:2:4-triazole

Coordinative Versatility of Guanazole [3,5‐Diamino‐1,2,4‐triazole]: Synthesis, Crystal Structure, EPR, and Magnetic Properties of a Dinuclear and a Linear Trinuclear Copper(II) Complex Containing Small Bridges and Triazole Ligands

“…The first structurally characterized (triazole)copper(II) compound to include µ-chloride ions was [{Cu(Htrz)Cl 2 } ϱ ], but it consists of an infinite chain with two Cl -and a single triazole ligand per pair of copper atoms instead of one Cl -and two triazole ligands. [34] To the best of our knowledge, only five Cu II compounds strictly comparable to 2 as regards bridging systems have been published to date (all have been mentioned above): one containing µ-fluoride anions (7), [23] three with chlorido bridges (3, 4, and 6; of which 3 and 4 have an unusual chelating tetradentate triazole ligand), and one in which the small bridging anion is the azido N 3 -group (5). [25] Table 3 lists several structural parameters, including coordination distances, which will be considered in the magnetism section.…”

A novel copper-based MOF material: Synthesis, characterization and adsorption studies

“…The first structures of coordination polymers have been already reported in the early 1960s [2][3][4], but with the synthesis of HKUST-1 (Cu 3 (btc) 2 , btc = 1,3,5-benzene tricarboxylate) and MOF-5 in 1999 [5,6], MOF materials became really popular. HKUST-1 and the recently presented DUT-6 possess impressive high specific surface areas [5,7,8].…”

1,2,4-Triazole complexes. V. The crystal structure of the layered compound poly-bis(thiocyanato-N)bis-μ-(1,2,4-triazole-N2,N4)cobalt(II) and its zinc(II) and copper(II) analogues

“…In these compounds 1,2-bridging trz units have been found. In CuCl2.trz (Jarvis, 1962) Cu n ions are bridged by C1-and trz groups along infinite chains. Ni3(trz)6(HEO)6(NO3)6.2H20 (Reimann & Zocchi, 1971) is built up of linear clusters of three Ni ~I ions bridged by six trz molecules.…”
