Product of a DMF Aminalization, Bis[bis(3,5-dimethylpyrazol-1-yl)(dimethylamino)methane]copper(II) Perchlorate−Bis(dichloromethane)

摘要: Bis[bis(3,5-dimethylpyrazol-1-yl)(dimethylamino)methane]copper(II) perchlorate−bis(dichloromethane), Cu(II)(1)2(ClO4)2·2CH2Cl2 , 2, is the unanticipated product of reaction tris(3,5-dimethylpyrazol-1-yl)methylsilane, 3, with Cu(II)(DMF)4 (ClO4)2. In title complex, Cu(II)(1)2 cations exhibit a tetragonal Cu(II)N6 geometry arising from coordination four pyrazole N atoms and two tertiary amine bis(3,5-dimethylpyrazol-1-yl)(dimethylamino)methane ligands, 1. The tridentate (N)3 ligands 1 coordinate copper facially one Cu−N (pyrazole) axial [Cu−N, 2.407(4) A] second equatorial 1.995(4) A]; crystallographic 2-fold symmetry that relates ligand to other. Cu(II)(1)2(ClO4)2·2CH2Cl2, CuC28H46Cl6N10O8·2CH2Cl2, crystallizes in monoclinic space group C2/c, = 26.278(5) A, b 8.835(2) c 20.655(4) β 120.73(3)°, Z 4, RF (RwF2) 0.049 (0.122) for 1979 observed reflections I > 2σ(I).
