Syntheses of supramolecular CuCN complexes by decomposing CuSCN: a general route to CuCN coordination polymers?

摘要: The solvothermal reaction of CuSCN with 1,2-bis(diphenylphosphino)ethane (dppe) yielded a coordination polymer, which was characterized to be complex CuCN and 1,2-bis(diphenylthiophosphinyl)ethane (dppeS2): [(CuCN)2(dppeS2)]n (1). identification 1 reveals that decomposed the sulfur transferred dppe, represents new example transformation inorganic organic sulfur. weak interactions between dppeS2 indicate may substituted by ligands strong ability. ligand 2,4,6-tris(2-pyridyl)-1,3,5-triazine (tpt) chosen as substitute ligand. Three novel polymers tpt were synthesized characterized: [Cu2(CN)2(tpt)]n (2) 3-D (10,3)-a network, (3) [Cu2(SCN)(CN)(tpt)]n (4) both 2-D (6,3) only 2 can obtained from directly. Interestingly, compounds 3 are genuine high-dimensional supramolecular isomers. During syntheses 2–4, single crystals isolated, indicates it also confirmed dppe. observed when temperature is relative high (>160 °C). At 140 °C, 5 containing attained no has been monitored in resulting filtrate.
