abstract in english:	In the reaction of maltol and its derivatives with a Mo(IV) cyano complex, three new salts were isolated and characterized by physicochemical measurements. The X-ray single crystal measurements of two salts of the formula (PPh 4 ) 2 [Mo(CN) 3 O(LL)] 3H 2 O, where LL = maltol or ethylmaltol, show a distorted octahe- dral geometry of the anions. The steric hindrance introduced by the ethyl group changes mainly the inter- molecular distances in the solid state and the network of hydrogen bonds. All the synthesized salts were compared and discussed with the family of NO, NN and OO donating [Mo(CN) 3 O(LL)] n groups. The role of the ligand protonation constant on the isolation of the products is presented by the synthesis of a (PPh 4 ) 2 [Mo(CN) 4 O(H 2 O)] 5H 2 O salt.
