Abstract

The structure of (NH4)2 CuCl4 · 2 H2O has been determined
from two-dimensional neutron data. The R index is 5.6% when
unobserved reflections are omitted. Two water oxygen atoms with
t he Cu-O distance of 1.98 A and two chlorine atoms with the
Cu-Cl distance of 2.30 A form a planar Cu(OH2 ) 2 Cl 2 grouping. Each
copper atom also forms two long Cu-Cl bonds of 3.03 A with the
other two chlorine atoms and so completes its distorted octahedral
configuration. The structure consists of distorted 1[Cu(OH2l2Ch]Ch
octahedra connected by hydrogen bonds and NH4 tetrahedra which
occupy holes between the three-dimensional network of octahedra.
