Dichlorido(N,N′-diisopropylpiperidine-1-carboximidamidato-κ2N,N′)titanium(IV)

Dichlorido(N,N′-diisopropyl­piperidine-1-carboximidamidato-κ2 N,N′)titanium(IV)

In the mononuclear title complex, [Ti(C(12)H(24)N(3))(2)Cl(2)], the Ti(IV) ion, located on a crystallographic inversion center, is six-coordinated by four N atoms from two N',N''-diisopropyl-N-carboxamidine anions and two chloride atoms in a distorted octahedral geometry. The dihedral angles between the piperidine groups and the NCN chelate rings are 51.5 (1) and 52.3 (1)°.

Bis[μ3-N′-oxidopyridine-2-carbox­imidamidato(2−)]bis­[μ2-N′-oxido­pyridine-2-carboximidamidato(1−)]tetra­pyridine­tetra­nickel(II) dinitrate

The title compound, [Ni(4)(C(6)H(5)N(3)O)(2)(C(6)H(6)N(3)O)(2)(C(5)H(5)N)(4)](NO(3))(2), is a tetra-nuclear nickel complex containing a single-decker cation, located on an inversion center. The two unique Ni(II) cations are N,N',N'',O-chelated by carbox-imid-amid-ate(2-) and carboximidamidate(1-) anions, forming a distorted four-coordinate planar structure, while the other two Ni(II) atoms are ...
