Synthesis and crystal structure of bis-[μ-N,N-bis-(2-amino-eth-yl)ethane-1,2-di-amine]-bis-[N,N-bis-(2-amino-eth-yl)ethane-1,2-di-amine]-μ₄-oxido-hexa-μ₃-oxido-octa-μ₂-oxido-tetra-oxido-tetra-nickel(II)hexa-tantalum(V) nona-deca-hydrate.

ABSTRACT: Reaction of K₈{Ta₆O₁₉}·16H₂O with [Ni(tren)(H₂O)Cl]Cl·H₂O in different solvents led to the formation of single crystals of the title compound, [Ni₄Ta₆O₁₉(C₆H₁₈N₄)₄]·19H₂O or {[Ni₂(κ⁴-tren)(μ-κ³-tren)]₂Ta₆O₁₉}·19H₂O (tren is N,N-bis-(2-amino-eth-yl)-1,2-ethanediamine, C₆H₁₈N₄). In its crystal structure, one Lindqvist-type anion {Ta₆O₁₉}^8- (point group symmetry ) is connected to two Ni^II cations, with both of them coordinated by one tren ligand into discrete units. Both Ni
