Аннотация

Reaction of cobalt hydroxide with the α,ω-dicarboxylic acid and 1,12-dodecanedioic acid under ambient conditions results in the formation of a trihydrate Co(C12H20O4)(H2O)3 (1). Single crystal X-ray diffraction studies show 1 to crystallise in the orthorhombic space group Pccn with cell parameters a = 40.2343(7) Å, b = 8.1519(1) Å, c = 9.1011(2) Å. The structure has a very pronounced two dimensional character, with a separation of hydrophobic n-alkyl chains from the carboxylate groups, the Co2+ cations and the water of crystallisation. The structure is discussed in respect of the structures of other known compositionally related compounds, including the dihydrate Co(C12H20O4)(H2O)2.
