The crystal of the title compound, [Zn(C(7)H(3)Cl(2)O(2))(2)(H(2)O)(2)](2)·[Zn(2)(C(7)H(3)Cl(2)O(2))(4)(H(2)O)(2)], consists of monomeric and dimeric Zn(II) complexes. Both complexes afford a six-coordinated coordination environment about the Zn atoms with cis-configuration ligands. The deprotonated hydr-oxy groups of the 3,5-dichloro-salicylaldehyde ligands bridge two metal cations, forming a ...

New pyrimido [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazines were synthesized via the cyclocondensation of alkyl-2-phenylhydrazinecarbodithioates as a binucleophile with 5-bromo-2,4-dichloro-6-methylpyrimidine as a bielectrophile , and replacement of C-7 chloro atom by hydrazine in ethanol as the solvent . This method has advantages over methods currently described in the literature for the con...

In the title compound, [Ni(C(7)H(3)Cl(2)O(2))(2)(C(3)H(7)NO)(H(2)O)], the Ni(II) ion is coordinated by four O atoms from two bidentate 2,4-dichloro-6-formyl-phenolate ligands, one O atom from a water ligand and one O atom from a dimethyl-formamide ligand in a slightly distorted octa-hedral environment. In the crystal structure, centrosymmetric dimers are formed though O-H⋯O and O-H⋯Cl hydrogen ...
