Synthese und Kristallstruktur von Ammin(μ3‐L‐glutamato)kupfer(II)

TLDR: In this article, the synthesis and crystal structure of ammine ammine complex is described, where the copper atoms exhibit a square-pyramidal coordination with two N atoms and two O atoms in the base plane and one O atom at the apex of the pyramid.

Abstract: Synthesis and Crystal Structure of Ammine(μ3-L-glutamato)copper(II) [Cu(L-Glu)H2O]·H2O reacts with aqueous ammonia to give the ammine complex [Cu(L-Glu)NH3] (1). 1 forms orthorhombic crystals, space group P 21212 with a = 1585,1(1) pm; b = 979,46(7) pm and c = 504,70(5) pm. In the crystal structure of 1 the copper atoms are linked by μ3-glutamate units to give a 2D layer structure. The copper atoms exhibit a square-pyramidal coordination with two N atoms and two O atoms in the base plane and one O atom at the apex of the pyramid. The crystal structure is stabilized by a 3D network of N–H···O hydrogen bridges.
