Synthesis and molecular structure of hetero-metallic cluster CpCoW(CO)2(S2C2B10H10)2 and binuclear half-sandwich Co complex [Cp*Co(S2C2B10H10)]2(bpo) with dichalcogenolate o-carboranyl ligands was written by Zhang, Jia-Sheng;Jin, Guo-Xin. And the article was included in Inorganic Chemistry Communications in 2008.Name: 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole This article mentions the following:
Cobalt and cobalt-tungsten binuclear carboranyl dithiolates were prepared and characterized by crystal structure determination The mononuclear 16-electron “pseudo-aromatic” dithio-o-carboranylcobalt complex [Cp’Co(S2C2B10H10)] (1a,b; Cp’ = η5-C5H5, η5-C5Me5) were prepared by treatments of [Cp’Co(CO)I2] with the dilithium carboranyl dithiolate Li2S2C2B10H10. Both of 1a and 1b react with 2,5-bis(4-pyridyl)-1,3,4-oxadiazole (bpo) to give dicobalt complexes [Cp’Co(S2C2B10H10)[(4-NC5H4-κN)-2,5-C2N2O-(4-C5H4N-κN)]CoCp'(S2C2B10H10)] (2a,b, same Cp’). Complex 1a reacts with tungsten(0) complex W(CO)3(py)3 to produce a heterobinuclear Co-W complex [CpCo(μ-S2C2B10H10)W(CO)2(S2C2B10H10)] (3a). The mol. structures of 1b, 2b and 3a have been determined by x-ray crystallog. In the experiment, the researchers used many compounds, for example, 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7Name: 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole).
2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Name: 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole
