O hydrogen bonds between the carboxyl groups. O hydrogen bonds, forming
a three-dimensional network.<br>
O hydrogen bonds, linking the independent molecules into dimers, may be
effective in the stabilization of the crystal structure.<br>
Rings A and B and rings B and C are trans-fused, while rings D and E are
cis-fused. N hydrogen-bonding interactions contribute to the stability
of the structure.<br>
The crystal packing is stabilized by van der Waals forces.<br>
The diacid anions and uncoordinated water molecules fill the space
between the layers. O hydrogen bond involving the NH imine H atom and
the phenolate O atom. The crystals were found to be twinned.<br>
Both five-membered rings have envelope structures.<br>
O hydrogen bonds and by short Cl.<br>
O hydrogen bonds and by short Cl. O hydrogen bonds link adjacent
molecules, forming a two-dimensional network.<br>
O hydrogen bonds that link adjacent molecules into one-dimensional
extended chains.<br>
O hydrogen bond, forming chains extended in the a-axis direction.<br>
The complex adopts octahedral geometry.<br>
O hydrogen bond, forming chains extended in the a-axis direction. O
hydrogen bonds link the molecules, forming a network, which may be
effective in the stabilization of the crystal structure.<br>
O hydrogen bond, forming chains extended in the a-axis direction. N
hydrogen bonds, leading to a chain structure. O interactions help to
form chains of molecules in the crystal structure.<br>
The carboxylate arms of the ligand chelate to the metal, which shows
square-antiprismatic coordination.<br>
O intramolecular hydrogen bonds lead to the formation of a sequence of
five-, six- and five-membered rings, respectively, which are
edge-fused.<br>
The piperidine ring has a distorted chair conformation. O hydrogen bond,
forming chains extended in the a-axis direction.<br>
O hydrogen bonds between the carboxyl groups.<br>
O hydrogen bonds between the carboxyl groups.<br>
