THE FIRST METAL-COMPLEX WITH NEUTRAL 1,2- BIS(PHENYLTRIAZENO)-BENZENEAS LIGAND - SYNTHESIS AND CRYSTAL-STRUCTURE OF PHN(3)(H)C6H4N3(H)PH)(PHN(3)C(6)H(4)N(3)(H)PH)(2)]

PhN(3)(H)C6H4N3(H)Ph}{PhN(3)C(6)H(4)N(3)(H)Ph}(3)] is obtained in aque ous ammonia by the reaction of CdSO4 with an excess of 1,2-bis(phenylt riazeno)benzene. It forms orange red, air stable prismatic crystals wi th the monoclinic space group P2(1)/c and a = 1217.7(2); b = 2161.8(6) ; c = 2008.3(5) pm; beta = 100.07(6)degrees; Z = 4. The compound is co mposed of mononuclear complexes in which the Cd atom is coordinated by one chelating bis(phenyltriazeno)benzene and two monodentate 1-phenyl triazenido-2-phenyltriazeno benzene anions in a distorted tetrahedral arrangement. The Cd-N distances are in the range of 220.7 to 239.7 pm.
