Lanthanide hydroxide cubane clusters anchoring ferrocenes: model compounds for fixation of organometallic fragments on a lanthanide oxide surface.

The reaction of the lanthanide trichloride hexahydrates [LnCl(3).6H(2)O] (Ln = Yb, Lu) with two equivalents of benzoylferrocenoylmethane resulted in the tetranuclear lanthanide hydroxo clusters [Ln(4)(mu(3)-OH)(4)(FcacacPh)(8)] (Ln = Yb (1), Lu (2); FcacacPh = benzoylferrocenoylmethanide). Compounds 1 and 2 are made up of a distorted tetranuclear lanthanide Ln(4)O(4) cubane core consisting of four mu(3)-oxygen atoms while the eight FcacacPh ligands build up the peripheral part of the cluster. These compounds contain the maximum number of ferrocene units anchored to any molecular metal-heteroatom framework reported so far and for which the X-ray structures are known.

A new structural form for a decanuclear copper(II) assembly.

The synthesis and structure of a novel decanuclear copper(II) cage is reported. The assembly of the cage is facilitated by the cumulative coordinative interaction of tert-butyl phosphonate, 2-pyridylpyrazole and hydroxide ligands with copper(II) ions. Magnetic studies of this decanuclear copper(II) cage indicate complex antiferromagnetic behaviour.

A new structural form of tin in a double O-capped cluster.

A novel hexameric organooxotin cage [{(n-BuSn)3(PhO)3O}2{HPO3}4] 1 has been assembled by the reaction of [n-BuSnO(OH)] with (PhO)2P(O)H. The structure of 1 consists of two O-capped Sn3 clusters that are attached to each other by four bridging tripodal [HPO3]2- ligands.
