Abstract:
In the title compound, [Ni(SCN)(C(16)H(32)N(4))]ClO(4)·H(2)O, the Ni(II) ion is coordinated by the four N atoms of the tetra-azacyclo-tetra-deca-4,11-diene macrocyclic ligand and by the S atom of a thio-cyanate anion. The perchlorate anion is rotationally disordered around one Cl-O bond between two orientations; the occupancies refined to 0.61 (4) and 0.39 (4). Inter-molecular O-H⋯N, N-H⋯O and N-H⋯N hydrogen bonds link two cations, two anions and two solvent water mol-ecules into a centrosymmetric cluster. The crystal packing is further stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

Coordination Number and Geometry
Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
