Untersuchungen an MM″ (NCS)4-Komplexen (M = NiII, FeII, ZnII; M″ = HgII, ZnII)Komplexe des Typs MM′(NCS)4 · xL M = NiII, FeII, ZnII; M″ = HgII, ZnII; x = 2, 4, 6; L = Nicotinamid (nia), Isonicotinsaiurehydroxid (inh) 2-Aminopyrimidin (2apm)] wurden dargestellt und charakterisiert durch Elementaranalyse, molare Leitfähigkeit, magnetisches Moment, IR- und Elektronenspektren.
Notes:
Coordination complexes of the type MM″(NCS)4 · xL M = Ni(II), Fe(II), Zn(II), M″ = Hg(II), Zn(II), x = 2, 4, 6 and L = nicotinamide (nia), 3-cyanopyridine (3-cpy), 4-cyanopyridine (4cpy), 4-aminopyridine (4apy), isonicotinic acid hydrazide (inh), 2-aminopyrimidine (2apm)l have been prepared and characterized by elemental analysis, molar conductance, magnetic moment, infrared and electronic spectral studies. Molar conductance data of NiZn(NCS), complexes are equivalent to 1:1 electrolyte. The infrared spectral studies indicate that only bridged thiocyanate groups are present in the complexes of the type NiHg(SCN)4 · 4L [L=3 and 4cpy, inh] and FeHg(SCN)4 · 2L [L = nia, 2apm], whereas both bridged and terminal thiocyanates are present in the complexes of the type NiHg(SCN)4 · 4L [L = nia, 3apy and ZnHg(SCN)4 · 2(inh). BOHR magneton values and electronic spectral data indicate an octahedral environment around nickel and iron in their complexes. Symmetry and group theory have also been used to establish the structure of the complexes.
