Two novel bis(2,9-dimethyl-1,10-phenanthroline)copper(I) complexes: [Cu(dmp)2]2(PF6)2·0.5(bpmh)·CH3CN and [Cu(dmp)2][N(CN)2]
摘要:
Two new salts of the cation [Cu-I( dmp)(2)](+) (dmp is 2,9- dimethyl-1,10- phenanthroline, C14H12N2), namely bis[ bis(2,9-dimethyl-1,10- phenanthroline-kappa(2) N, N') copper( I)] bis( hexafluorophosphate) hemi[ bis(4-pyridylmethylidene) hydrazine] acetonitrile solvate, [Cu(C14H12N2)(2)](2)(PF6)(2) center dot 0.5C(12)H(10)N(4) center dot C2H3N or [Cu( dmp)(2)](2)(PF6)(2) center dot 0.5(bpmh) center dot CH3CN [bpmh is bis(4-pyridylmethylidene) hydrazine, C12H10N4], ( I), and bis( 2,9-dimethyl- 1,10- phenanthroline-kappa(2) N, N') copper( I) dicyanamide, [Cu(C14H12N2)(2)](C2N3) or [Cu( dmp)(2)][N(CN)(2)], ( II), are reported. The Cu - N bond lengths and the distortion from idealized tetrahedral geometry of the dmp ligands are discussed and compared with related compounds. The bpmh molecule in ( I) is pi-pi stacked with a dmp ligand at a distance of 3.4 angstrom, rather than coordinated to the metal atom. The molecule lies across an inversion center in the crystal. In ( II), the normally coordinated dicyanamide molecule is present as an uncoordinated counter-ion.
