Inorganic Coordination Polymers. Part XIX. Steric Effects of Hydrocarbon Side Groups on the Structure and Properties of Zinc(II),Cobalt(II),Manganese(II),Nickel(II) and Copper(II) Bis(Phosphinates).

摘要

The metal (II) dialkylphosphinates M(OPR2O)2 (with M = Mn, Co, Ni, Cu and Zn; R = -C(CH3)3, -CH2CH2CH2CH3 and -CH(CH3)-CH2CH2CH3) have been investigated. The structures of the complexes with straight chain R substituents vary for the different metals and include polymers with both octahedrally and tetrahedrally coordinated metal centers. On the other hand, the metal(II) phosphinates that contain bulky alkyl R substituents all appear to have the same structure, which contains tetrahedrally coordinated metal centers and symmetrically bridging O,O' phosphinate groups.
