N2  - A number of mono and bis(che1ate) complexes of iron(II) and 2,9-dimethyl-1,10-phenanthroline (dmp) have been isolated. The mono complexes are of general formula FedmpX2, where X=Cl, Br, I ; 2X=SO4. They are yellow to brown in colour except for the sulphato complex, which is pink. Conductivity and cryoscopic measurements indicate that the halogeno compounds are nonelectrolytes and monomeric. The magnetic moments range from 5.1 to 5.4 B.M. The evidence points to these compounds being four-coordinate tetrahedral complexes. The bis(che1ate)complexes are Fe(dmp)2(NO3)2(H2O)2 and Fe(dmp)2(NO3)(ClO4)(H2O)2, both yellow crystalline substances. They are 1 : 1 electrolytes in nitrobenzene and nitromethane. The magnetic moments are 5.2 B.M. for the dinitrate and 5.05 B.M. for the nitrate-perchlorate. According to their infrared spectra, each compound in the solid state appears to contain covalently bound nitrate and is most probably six-coordinate.
