Bis4-(2-carbamoylhydrazin-1-yl­idene-κ2 N 1O)-5-hydroxy­methyl-2-methyl­pyridinium-3-olato-κO 3cobalt(II) dinitrate dihydrate

摘要

The asymmetric unit of the title compound, [Co(C9H12N4O3)2](NO3)2·2H2O, consists of a discrete cationic [Co(PLSC)2]²⁺ complex unit [PLSC is 4-(2-carbamoylhydrazin-1-yl­idene)-5-hydroxy­methyl-2-methyl­pyridinium-3-ol­ato], two NO3 ⁻ and two water mol­ecules. The two tridentate PLSC ligands of the cation are zwitterions related to each other by a non-crystallographic C 2 axis. The Co^II ion is in a disorted octa­hedral coordination environment. The crystal structure is composed of alternating NO3/H2O and complex layers supported by extensive C—H⋯O, N—H⋯O and N—H⋯N hydrogen bonding.
