Popis: The crystal and molecular structures of ethoxido-oxo-bis(1,5,9,13-tetrathiacyclohexadecane)-μ-oxodimolybdenum- (IV)trifluoromethanesulfonate hydrate are reported. The complex crystallizes in the orthohombic space group Pn21 a with four molecules per unit cell of dimensions a=16.149(2)A, b=20.477(4)A, c=15.217(2)A and V=5381(2)A3. Full matrix least squares refinement gave final discrepancy factors of R1=.076 and R2=.094 for 3147 data having F2 > 2.5σ(F2). The molecular structure is highlighted by a linear O-Mo=O[sbnd]Mo=O unit. The two macrocycles coordinate each Mo atom in a “planar” tetradentate mode, and are staggered ∼ 43° relative to one another.
