Abstract

The complexes M(L1, 2)2 · nH2O, where M = Co(II), Ni(II), Cu(II), and Zn; n = 2 and 3, were synthesized by the reaction of Co(II), Ni(II), Cu(II), and Zn(II) chlorides with 2,4,7-trinitro-9-fluorenone oxime (HL1) and 2,4,5,7-tetranitro-9-fluorenone oxime (HL2) and identified. It was shown that HL1, 2 were coordinated by metal cations in the anionic form in a 2: 1 ratio. A single crystal of the solvate of HL2 with acetonitrile (1: 1) HL2 · NCCH3 was isolated, and its crystal structure was determined. The spectral characteristics were determined, and the acidity constant of HL1 was calculated. The structures for the synthesized complexes were proposed.
