A copper(II) complex of the non-symmetric bidentate ligand 2-{[6-(di-methyl-amino)-pyrimidin-4-yl]sulfan-yl}pyrimidine-4,6-di-amine (1) is reported. The single-crystal X-ray structure of aqua-aqua/chlorido-(0.49/0.51)-copper(II) 0.49-chloride 1.51-hydrate, [CuCl(CHNS)(HO)]Cl·1.51HO or [(1)Cl(HO)Cu]0.49Cl·1.51HO, exhibits distorted square-pyramidal geometry around the metal centre, with disorder in the axial position, occupied by chloride or water. The six-membered metal-chelate ring is in a boat conformation, and short inter-molecular S⋯S inter-actions are observed. In addition to its capacity for bidentate metal coordination, the ligand has the ability to engage in further supra-molecular inter-actions as both a hydrogen-bond donor and acceptor, and multiple inter-actions with lattice solvent water mol-ecules are present in the reported structure.
报道了一种非对称双齿配体2-{[6-(二甲基氨基)-嘧啶-4-基]硫烷基}嘧啶-4,6-二胺(1)的铜(II)配合物。水合-水合/氯代(0.49/0.51)-铜(II)0.49-氯化物1.51-水合物,[CuCl(CHNS)(H₂O)]Cl·1.51H₂O或[(1)Cl(H₂O)Cu]0.49Cl·1.51H₂O的单晶X射线结构显示,金属中心周围呈现扭曲的四方锥几何构型,轴向位置存在无序,由氯离子或水分子占据。六元金属螯合环呈船式构象,并且观察到短的分子间S⋯S相互作用。除了具有双齿金属配位能力外,该配体还能够作为氢键供体和受体参与进一步的超分子相互作用,并且在所报道的结构中存在与晶格溶剂水分子的多种相互作用。
