The crystal structure of the title compound, tris(1,10-phenanthroline-N,N')
iron(II) bis[1,2-benzisothiazol-3(2H)onate 1,1-dioxide] 1,2-benzisothiazol-
3(2H)-one 1,1-dioxide hexahydrate, [Fe(C12H8N2)(3)](C7H4NO3S)(2).C7H5NO3S .
6H(2)O, at 120 K consists of slightly distorted octahedral [Fe(phen)(3)](2
+) cations (phen is 1,10-phenanthroline), two saccharinate anions and a fre
e saccharin molecule, as well as six waters of crystallization. The compoun
d has been confirmed as diamagnetic low-spin iron(II) by magnetic measureme
nts. There is extensive hydrogen bonding leading to a three-dimensional net
work.
