The asymmetric unit of the title compound, [Cu(C₉H₁₀N₃O₃)Cl], contains two independent molecules with similar structures. The Cu^II cation is N,O,O′-chelated by the deprotonated Schiff base ligand and is further coordinated by a Cl⁻ anion in a distorted ClNO₂ square-planar geometry. In the crystal, adjacent molecules are linked by N—H⋯O and N—H⋯Cl hydrogen bonds, forming a two-dimensional network parallel to [100].

Comment top

Salicylaldehyde thiosemicarbazone and its subsituted derivatives are Schiff bases that are capable of N,N',O-chelation to transition metal ions, a feature that has been documented in a plethora of metal derivatives. Several copper derivatives have been reported (Wang et al., 2008; Patole et al., 2001). The Cu^II atom in CuCl(C₉H₁₀N₃O₃) (Scheme I) is N,N',O-chelated by the deprotonated Schiff base, and it exists in a square planar environment in the two independent molecules (Fig. 1). Adjacent molecules are linked by N–H···O and N–H···Cl hydrogen bonds to form a two-dimensional network (Table 1).

Experimental top

The Schiff base was prepared by heating 2-hydroxy-4-methoxybenzaldehyde (0.152 g,1 mmol) and semicarbazide hydrochloride (0.111 g,1 mmol) for 3 h. Copper(II) dichloride dihydrate (0.170 g, 1 mmol) was added to the solution and reflux was continued for another 2 h. Dark green colored crystals were isolated from the cool solution.
