Title: Crystal Structure of the Dinuclear (R,R)-tartrato Nickel(II) Complex: [Ni2((R,R)-C4H4O6)2(H2O)4]2 10H2O
Abstract: The dinuclear (R,R)-tartrate nickel(II) complex, [Ni2((R,R)-C4H4O6)2(H2O)4]2·10H2O, has been synthesized and its crystal structure has been determined by single-crystal X-ray diffraction. The structure consists of two independent nickel (R,R)-tartrate units and ten water molecules. Each unit contains two (R,R)-tartrato dianions chelated to two nickel ions (5.049(2) and 4.994(2)Å for Ni(1)-Ni(2) and Ni(3)-Ni(4)), with the use of two hydroxyl oxygen atoms and two carboxyl oxygen atoms as donor atoms. The coordination geometry for each nickel ion can be described as octahedral.
