Abstract:
... We demonstrate the application of magnetic forces for the simultaneous trapping of two types of particles, magnetic and diamagnetic, via a single set of magnets. Furthermore, we show how this simple setup can be employed for performing assays with a negative control, or for achieving multiple simultaneous analyses. ...

Abstract:
... The 1 : 2 reactions of 4,6-bis[N,N-bis(2′-pyridylmethyl)aminomethyl]-2-phenylpyrimidine (Lᴹᵉ) and Mnᴵᴵ, Coᴵᴵ, Niᴵᴵ and Cuᴵᴵ chloride salts in MeOH gave the tetranuclear complexes [Mnᴵᴵ₄(Lᴹᵉ)₂Cl₈]·2H₂O (1), Coᴵᴵ₄(Lᴹᵉ)₂Cl₈·10H₂O (2), [Ni₄ᴵᴵ(Lᴹᵉ)₂Cl₄]Cl₄·8H₂O (3) and [Cuᴵᴵ₄(Lᴹᵉ)₂Cl₆]Cl₂·8H₂O (4), respectively. X-ray crystal structure determinations carried out on three of the complexes revealed that ...
