Background-Although several studies have documented a higher prevalence of psychiatric disorders in children of depressed than nondepressed parents, previous research was conducted in predominantly White, middle, or upper-middle class populations. Only limited information is available on psychiatric disorders and psychosocial functioning in children of low-income depressed mothers.

The treatment of FcLi 2 ؒTMDA with pyS-Spy (py = 2-pyridyl) leads to the new ferrocene derivative Fc(Spy) 2 1. The reaction of 1 with gold() or gold() complexes gives heterometallic complexes of the type [ {Au(C 6 F 5 )} 2 {Fc(Spywhere the coordination of the gold centres takes place through the nitrogen atoms as evidenced by two crystal structure determinations. Complex 1 also reacts with silver complexes to afford derivatives such as [Ag(OTf ){Fc(SpySubstitution of the triflate ligand in [Ag(OTf ){Fc(Spy) 2 }] by bidentate ligands such as phen or SdppmS gives [Ag(phen){Fc(Spy) 2 }]OTf or [Ag(SdppmS){Fc(Spy) 2 }]OTf. The silver complex [Ag 2 {Fc(Spy) 2 } 3 ](OTf ) 2 has also been characterised by X-ray diffraction showing three 1,1Ј-bis(2-pyridylthio)ferrocene ligands bridging two silver atoms.DALTON

The ferrocene ligand 6‐[(ferrocenylmethyl)amino]‐2‐picoline, FcCH2NHpyMe [Fc = (η5‐C5H5)Fe(η5‐C5H4)], has been prepared by treatment of FcCH2NMe2 with 6‐amino‐2‐picoline, NH2pyMe. The coordination chemistry with group 11 metals has been studied and several complexes with coordination of the metal atom to the pyridine nitrogen atom, such as [M(PPh3)(FcCH2NHpyMe)]OTf, [Au(C6F5)(FcCH2NHpyMe)] and [AuR3(FcCH2NHpyMe)] (M = Au, Ag; R3 = (C6F5)3, (C6F5)2Cl; OTf = trifluoromethanesulfonate), have been obtained. The complex [Cu(FcCH2NHpyMe)2]PF6 has also been synthesised with a probable coordination of the copper centre to the pyridine and amine nitrogen atoms. Deprotonation of the NH group allows the synthesis of dinuclear complexes of the type [M2(PPh3)2(FcCH2NpyMe)]X or [Au2(C6F5)(PPh3)(FcCH2NpyMe)] with a mixed pyridine−amide ligand. Some of the complexes have been characterised by X‐ray diffraction and show the presence of intramolecular aurophilic interactions in the dinuclear complex and intermolecular interactions leading to chains in the mononuclear complex. Other types of secondary bonds are present in these structures, such as hydrogen bonding and weak η2 interactions between the gold centre and the cyclopentadienyl ring. (© Wiley‐VCH Verlag GmbH & Co.
