The Fe3’ and OHin this unit are chemically bound to each other. If the concentration of ferric iron is high enough, the formation of complex species may also involve association of monomeric units to give dimers “Polynuclear” complexes are defined by Baes and Mesmer (1976, p. 2) as complexes containing more than one cation. This is a broader definition than the one implied above for polymeric s...

The ionic title complex, [Cu(C(4)H(13)N(3))(2)](2)[Cr(NCS)(4)(NH(3))(2)](3)(NCS)·14C(2)H(6)OS·H(2)O, consists of complex [Cu(dien)(2)](2+) cations [dien is N-(2-amino-eth-yl)ethane-1,2-diamine], com-plex [Cr(NCS)(4)(NH(3))(2)](-) anions, an NCS(-) counter-anion and uncoordinated dimethyl sulfoxide (DMSO) and water solvent mol-ecules. One of the Cr atoms lies on an inversion center, while the se...

A new synthetic method for polynuclear lanthanoid complexes that are embedded in molecular polyoxotungstates has afforded the highest nuclearity polyoxometalate-encapsulated Gd complex and the first decanuclear Yb complex of any sort to be structurally characterized.

The primary objective was to understand more deeply the molecular mechanism underlying different antitumor effects of dinuclear Pt(II) complexes containing aromatic linkers of different length, {[cis-Pt(NH(3))(2)Cl](2)(4,4'-methylenedianiline)}(2+) (1) and {[cis-Pt(NH(3))(2)Cl](2)(alpha,alpha'-diamino-p-xylene)}(2+) (2). These complexes belong to a new generation of promising polynuclear platin...

The first water soluble and crystallographically determined polynuclear Mn(II) complex, with water molecules bridging every two Mn centers, is reported. This is an unusual feature in 1D oligomer Mn(II) compounds with a nuclearity higher than 2. The polymer structure is largely preserved in water.

A nanoscopic {Fe60} coordination cage (approximately 3 nm) was prepared by the self assembly of a partially blocked tricyanidoferrate(iii) complex and tris(alkoxo)-based iron(iii) coordination motifs. This cage is a rare example of a mixed cyanido/alkoxo-bridged high nuclearity complex and it exemplifies the great potential of this new synthetic route to generate uncommon molecular architecture...
