Sonochemical synthesis and crystal structure of di-methyl-ammonium bis-[3-carb-oxy-2-(di-methyl-amino)-propano-ato-?2 N,O 1]chlorido-chromium(II) monohydrate.

ABSTRACT: The title complex, [(CH3)2NH2][Cr(C6H10NO4)2Cl]·H2O, was synthesized sonochemically. The complex anion consists of a chromium(II) ion ligated by two 3-carb-oxy-2-(di-methyl-amino)-propano-ate anions. They coordinate in a bidentate manner, with a carboxyl-ate oxygen atom and the nitro-gen atom cis to each other in the equatorial plane, while the apical position is occupied by a Cl- ion. Hence, the chromium(II) ion is five-coordinate with a quasi-ideal square-pyramidal geometry; ?5 parameter = 0.01. The complex crystallizes as a monohydrate and in the crystal, the water mol-ecule and the di-methyl-ammonium counter-ion link the complex cations via N-H?O, N-H?Cl, Owater-H?O, O-H?Owater and O-H?O hydrogen bonds, forming a supra-molecular framework. There are also a number of C-H?O hydrogen bonds present that reinforce the framework structure. The crystal studied was refined as a racemic twin.
