The difference interaction between complexes 1, 2 and DNA should be ascribed to their different structures.
Deepali Prashar et al [17]. using a host-guest chemistry to noncovalently tether a dicarboxylate platinum (II) chelate with β-cyclodextrin to enhance transport and cytotoxicity of the platinum complex.
The influence of the compounds on the tertiary structure of DNA was determined by their ability to modify the electrophoretic mobility of the covalently closed circular (form I) and open (form II) of pBR322 plasmid DNA.
In contrast, complex 2 does not seem to modify the tertiary structure of DNA.

The tertiary structure of HPCs is the structure of solids, i.e. it is determined by solidstate laws [3].
At the same time, the space group of the crystal structure remained preserved.
The results depicted in Fig.6 indicate that the influence on Keggin anion structure is not only the function of polarizability or ionic size.

It has been reported that addition of metal ions can help to improve the crystallinity of the MoS2 typed structure and stacking of primastic layer. [8]
Fig. 1 XRD patterns of undoped MoS2 and Ni-doped MoS2 with different Ni/Mo ratio (RSC advance doi: 10.1039/c3ra42340a, Reproduced by permission of The Royal Society of Chemistry)
SEM was used to observe the morphology of as prepared MoS2.
Fig. 2 SEM image of undoped MoS2 at low magnification (a), at high magnification (b); SEM image of Nickel doped MoS2 at low magnification (c) and high magnification (d); EDS spectrum of Nickel doped MoS2 (NM2) (inset in figure d) (RSC advance doi: 10.1039/c3ra42340a, Reproduced by permission of The Royal Society of Chemistry) It is noteworthy the overpotential of Ni-doped sample has decreased compared with that of undoped sample, and a lowered overpotential for HER means an improved efficiency.
The increased activity of HER for Ni-doped MoS2 might be related to the modified electronic edge structure resulting from the nickel doping which is similar to cobalt doping.
(NM2: Ni:Mo=1:20 mole ratio; NM1 Ni:Mo=1:40 mole ratio; and NM3 Ni:Mo=1:10) (RSC advance doi: 10.1039/c3ra42340a, Reproduced by permission of The Royal Society of Chemistry) Conclusion A series of Ni-doped MoS2 microspheres have been prepared via facile hydrothermal synthesis.
