Solvent-induced structural transformation from heptanuclear to decanuclear [Co-Ln] coordination clusters: trapping of unique counteranion and understanding of aggregation pathways
Original language description
Five new cobalt(ii/ili)-lanthanide(m)-based coordination aggregates, [Ln(3)(III)Co(2)(II)Co(2)(III)(L1)(2)(O2CCMe3)(8)(OH)(4) (OMe)(2)(H2O)(4)]center dot Ln(eta(1)-O2CCMe3)(2)(eta(2)-O2CCMe3)(2)(MeOH)(2)center dot 2MeOH center dot 2H(2)O (where Ln = Tb (1), Ho (3), and H(2)L1 = N-(2-hydroxyethyl)-salicylaldimine), (Tb3Co3Co4III)-Co-III-Co-II(L1)(4)(O2CCMe3)(9)(OH)(10)(H2O) (4) and Ln(3)(III)Co(2)(II)CoT (L1)(4)(O2CCMe3)(10)(OH)(10) (Ln = Dy (5), Ho (6)) have been synthesized and characterized, including structural analysis via single-crystal X-ray diffraction. The dysprosium analogue (2) of 1 and 3 was previously reported by us. The heptanuclear monocationic clusters in 1 and 3 were formed by placement of seven metal ions (4 Co and 3 Ln) in a vertex shared dicubane structure from the control of two Schiff base anions and crystallized in the presence of in situ generated and literature unknown counter anions Tb(eta(1)-O2CCMe3)(2)(eta(2)-O2CCMe3)(2)(MeOH)(2)(-) and Ho(eta(1)-O2CCMe3)(2)(eta(2)-O2CCMe3)(2)(MeOH)(2)(-). Interesting solvent-induced cluster structure transformation was observed on dissolving the heptanuclear aggregates in MeCN for the formation of decanuclear clusters 4-6. These high nuclearity clusters consist of a vertex shared heptanuclear dicubane part and a curved trinuclear chain linking the two cubic halves. The dicubane unit differs from that of the heptanuclear precursors in the presence of Co-II/III at the shared vertex as opposed to Ln(III) and the absence of OMe- bridges. HRMS (+ve) analysis shed light on the pathway of formation of these heptanuclear molecules, while at the same time revealing a different aggregation process for the decanuclear clusters.
