Bis[4-amino-N-(4-methylpyrimidin-2-yl-κN 3)benzenesulfonamidato-κN](2,2′-bipyridine-κ2 N,N′)mercury(II)

چکیده
The complete mol-ecule of the title complex, [Hg(C11H11N4O2S)2(C10H8N2)], is generated by crystallographic twofold symmetry, with the mercury cation lying on the rotation axis. The mercury coordination polyhedron can be described as tetra-hedral (from the N,N'-bidenate bi-pyridine mol-ecule and the sulfonamide N atoms of the sulfamerazine anions) or as squashed trigonal-prismatic, if two long (> 2.80 Å) Hg-N bonds to pyrimidine N atoms are included. The dihedral angle between the aromatic rings in the anion is 73.3 (2)°. In the crystal, N-H⋯(N,O) and N-H⋯N hydrogen bonds link the mol-ecules into a three-dimensional network.

The title complex, [Co(C(10)H(9)N(4)O(2)S)(2)(C(3)H(7)NO)(2)], lies across an inversion center. The Co(II) atom is coordinated in a slightly distorted octa-hedral geometry by four N atoms from two bidentate 4-amino-N-(pyrimidin-2-yl)benzene-sulfonamidate (sulfadiazine) anions and two O atoms from two dimethyl-formamide (DMF) ligands. The dihedral angle between the benzene and pyrimidine rings i...
