In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Ligand Conformation Enforces Trigonal Bipyramidal Coordination Geometry in a New Dinuclear Bis(pyrazolato)-Bridged Copper(II) Complex: Synthesis, Crystal Structure, and Properties of [Cu(Npy2pz)]2(ClO4)2·2CH3CN, published in 2005-10-31, which mentions a compound: 948552-36-1, mainly applied to copper pyridinylmethylpyrazolylmethylamine preparation structure antiferromagnetism; crystal structure copper pyridinylmethylpyrazolylmethylamine dinuclear; pyridinylmethylpyrazolylmethylamine conformation effect copper coordination geometry, SDS of cas: 948552-36-1.
The reaction of Cu(ClO4)2·6H2O with the new tripodal ligand HNpy2pz (N-bis[(pyridin-2-yl)methyl][(1H-pyrazol-3-yl)methyl]amine) in the presence of 1 equiv of NEt3 gave a doubly pyrazolato-bridged dicopper(II) complex, [Cu(Npy2pz)]2(ClO4)2·2MeCN (1). The crystal structure of 1 was determined by x-ray crystallog. and was found to consist of two nearly identical discrete dinuclear mols. with bis(pyrazolato) bridges. The Cu(II) ion has a trigonal bipyramid geometry achieved by the coordination of an aliphatic N, two pyridine moieties, and two pyrazolato nitrogens. Variable temperature-dependent magnetic data show that antiferromagnetic interactions operate in 1 as a result of the binding angle of the pyrazolato bridge. In solution, the stability of the dinuclear cation, [Cu(py2pz)]22+, is highly dependent on the concentration, as indicated by ESI-MS, ligand field, cyclic voltammetry, EPR, and 1H NMR studies.
