Paramagnetic, flexible organometallic dithiolene complexes associating cyclopentadienyl (Cp) and dithiolate (dt) ligands, such as CpM(dt), Cp2M(dt), or CpM(dt)2, are investigated in the solid state through their structural and magnetic properties. The degree of delocalization of the spin density between the metal and the dithiolene fragments in a given complex, its varying molecular geometry and frontier orbitals, and the structures adopted in the solid state are intimately correlated and adapt mutually to each other. A variety of magnetic structures follows, from noninteracting spins to dyads, spin chains, spin ladders, or antiferromagnetic ground state, the detailed properties of which are highly sensitive to "minor" molecular modifications.
通过其结构和磁性性质，对结合环戊二烯基（Cp）和二硫醇盐（dt）配体的顺磁性、柔性有机金属二硫烯配合物，如CpM(dt)、Cp2M(dt)或CpM(dt)2进行了固态研究。在给定配合物中，金属和二硫烯片段之间自旋密度的离域程度、其变化的分子几何形状和前沿轨道，以及固态中采用的结构密切相关且相互适应。由此产生了多种磁性结构，从非相互作用自旋到二元体、自旋链、自旋梯或反铁磁基态，其详细性质对“微小”的分子修饰高度敏感。
