A novel dinuclear manganese(II) compound incorporating two bis(imidazolyl) based ligands with single μ2-η1:η1-carboxylato bridges. Molecular and crystal structure and magnetic properties of [Mn2Cl(BIP)(HBIMAM)(H2O)5]Cl3·4H2O (BIP=3,3-di(2-1H-2-imidazolyl)propanoate; BIMAM=N-methyldi(1H-2-imidazolyl)methanamine)

Metal–organic frameworks based on tri- and penta-nuclear manganese(ii) secondary building units self-assembled by a V-shaped silicon-containing dicarboxylate

SBUs consisting in penta- or trinuclear manganese(ii) are held together by cpdps²- or cpdps²- and Hcpdps- species derived from bis(p-carboxyphenyl)diphenylsilane in 2D (4,4) coordination polymers. Magnetic, thermal and moisture behaviors are studied.

A rare example of nickel(ii) chains based on a heteroscorpionate-like ligand with quadruple imidazolyl interactions

The first nickel(ii) complex with the heteroscorpionate-like bridging ligand DIMMAL (2-di1H-2-imidazolylmethylmalonate), [Ni(DIMMAL)(H2O)3]n·3nH2O (1), is a one-dimensional coordination polymer whose structure shows regular Ni(ii) chains with H-bonding inter-chain interactions and a rare example of a Quadruple Imidazolyl Embrace (QIE). The Ni(ii) chain shows a weak antiferromagnetic interaction that can be modelled with a regular S = 1 chain model including a zero field splitting with g = 2.270, J = -1.5 cm(-1) and D = -2.26 cm(-1).
