Abstract
The title dinuclear complex, [(cis-MoO2L)(μ-O)(cis-MoOL(OH2)], was characterized as a chloroform solvate. In this structure, one Mo atom features a cis-[MoO2]2+ core to which is also bonded a dinegative, tridentate S-benzyl 3-(2-hydroxyphenyl)methylenedithiocarbazate ligand (= L), via sulfur-, oxygen-, and nitrogen-donors, and a water molecule completes the distorted octahedral coordination geometry. A similar NO4S donor set is found for the other Mo atom but in this case, the water molecule is substituted by a bridging oxo atom derived from the first Mo species. Two dimers associate via cooperative O–H⋯O hydrogen bonds to form a supramolecular dimer which, in turn, are linked into supramolecular chains via O–H⋯N hydrogen bonding. The complex crystallizes in the triclinic space group P-1 with a = 10.4714(12) Å, b = 10.7627(14) Å, c = 16.708(2) Å, α = 87.916(7)°, β = 76.249(6)°, γ = 83.610(7)°, and Z = 2.
Index Abstract
Dinuclear [(cis-MoO2L)(μ-O)(cis-MoOL(OH2)], characterized as a chloroform solvate, with octahedral Mo centers, are connected into supramolecular dimers via O–H⋯O hydrogen bonding which are connected via O–H⋯N hydrogen bonds into chains.
