Synthesis and Crystal Structure of a Macrocycle [Cu(dadm)(mal)(H_2O)]_2·02H_2O |
|
| Abstract: | The reaction of 4,4?-diaminodiphenylmethane (dadm), malonic acid (H2mal) and Cu(NO3)2 in aqueous solution results in a discrete binuclear Cu(II) macrocycle: [Cu(dadm)(mal)- (H2O)]22H2O. It crystallizes in monoclinic, space group P21/c with a = 15.231(3), b = 11.847(2), c = 9.801(2) ? b = 106.75(3)o, V = 1693.5(6) 3, Z = 2, C32H40Cu2N4O12, Mr = 799.76, Dc = 1.568 g/cm3, ?(MoKa) = 0.71073 ? = 1.325 mm-1, F(000) = 828, the final R = 0.0531 and wR = 0.1244 for 3421 observed reflections with I > 2s(I). Each Cu(II) is coordinated by two oxygen atoms from a mal ligand, two nitrogen atoms from two dadm ligands and a water oxygen atom to form a triangle bipyramidal motif. The title compound possesses a distorted macrocycle enclosed by dadm with approximate dimensions of 8.3 ??5.9 ? |
