Abstract

The synthesis and crystal structure analysis of the diamagnetic complex [MoO2(HL)H2O]Cl · H2O (HL = monoanion of salicylaldehyde thiosemicarbazone) are reported. The complex crystallizes in the space group P21/a (No. 14) with a = 11.003(1), b = 8.444(1), c = 15.364(1) Å, β = 104.96(1)̇, V = 1379.1(2) Å3. X-ray structure determination revealed that the complex possesses the usual cis-MoO2 2+ core and that the thiosemicarbazide ligand is present as a monoanionic tridentate donor coordinating through ONS. According to a search in the Cambridge Structural Database (state April 1994) this complex is the first in which the sixth coordination site at Mo(VI) is occupied by a water molecule forming a distorted octahedral coordination geometry together with the tridentate ligand.
