The Interaction of α‐Hydroxycarboxylic Acids with Metal Ions: Lactic Acid (H2L1) and 2‐Methyllactic Acid (H2L2) with Cobalt(II) Crystal and Molecular Structures of [Co(HL1)2(H2O)2]·H2O and [Co(HL2)2(H2O)2]

Abstract:	The cobalt(II) complexes Co(HL¹)₂(H₂O)₂]·H₂O) ( 1 ) and Co(HL²)₂(H₂O)₂]( 2 ) (HL¹)^‐ = (/plusmn;)‐lactate, (HL²)^‐ = 2‐Methyl‐lactate] were prepared and characterized structurally. The cobalt atom is in a distorted octahedral environment in both compounds. Both α‐hydroxycarboxylato ligands are O, O'‐bidentate chelating monoanions. The presence of a lattice water molecule in 1 makes its supramolecular organization different from that of 2 . The thermal behaviour of both compounds was also investigated.
