Abstract:
In the structure of the title compound, [CdCl2(C4H8N2S)2], the Cd(II) atom is coordinated by two chloride ions and two 1,3-diazinane-2-thione (Diaz) mol-ecules through their S atoms. The geometry around the Cd(II) atom is distorted tetra-hedral, with bond angles in the range 101.55 (7)-117.91 (8)°. The CH2 groups of one Diaz ligand are disordered over two sets of sites with an occupancy ratio of 0.711 (12):0.289 (12). The mol-ecular structure is stabilized by intra-molecular N-H⋯Cl hydrogen-bonding inter-actions, generating a butterfly syn conformation. Inter-molecular N-H⋯Cl and N-H⋯S inter-actions lead to the formation of a three-dimensional network structure. The structure has been determined from a crystal twinned by nonmerohedry, by a 180° rotation around the reciprocal c axis. The twin ratio refined to 0.8866 (6):0.1134 (6).

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,...
Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
