Binuclear Metal

The crystal and molecular structures have been determined, by single-crystal X-ray methods, for each of the isomorphous set of divalent binuclear metal derivatives of 1,3-diphenyltriazene, abbreviated as dptH, [M(dpt)2]2 where M = Ni, Pd, and Cu. The crystals are composed of discrete molecular units, of composition M2(dpt)4, which have a syn-syn structure analogous to that of copper(II) acetate monohydrate with pairs of closely separated metal atoms held together by the terminal nitrogen atoms of four ligand groups in such a way that the environment of each metal atom is almost square-planar. The interatomic distances between the pairs of metal atoms, 2.395(3), 2563(1), and 2.441(2) Ǻ for the Ni, Pd, and Cu compounds, are strongly suggestive of metal-metal bonding. The two N4-planes are almost parallel but the two sets of coordinating nitrogen atoms are twisted markedly from the eclipsed configuration, the average angle of rotation being about 15°. Crystals of each complex are triclinic with space group P 1. The unit cell parameters in the order of a, b, c, α, β, and γ are 10.335(3), 15.84(1), 13.546(3)& 100.48(5), 94.47(2), 102.57(3)° for Ni2(dpt)4; 10.486(1), 15.791(2), 13.751(1)Ǻ, 99.48(1), 93.61(1), 104.37(1)° for Pd2(dpt)4; 10.373(3), 15.916(5), 13.612(3) Ǻ, 99.51(2), 94.85(3), 102.33(2)° for Cu2(dpt)4. The structure of the nickel complex was solved by the Patterson-Fourier method and the atomic parameters found for this structure were used as the basis of the structure determinations of the isomorphous copper and palladium compounds. All three structures were refined by a block-diagonal least-squares method using 3300 (photographic data) 4065 (counter) and 2753 (counter) independent non-zero terms for the nickel(II), palladium(II) and copper(II) compounds respectively, converging with R values 0.13 (isotropic), 0.056 (anisotropic) and 0.069 (isotropic) respectively.

Iodo Derivative

The reactions of Pd(CO)X (X = Cl, Br) with bis(diphenylphosphino)methane (dpm) and its arsenic analogue, dam, have been investigated. The iodo complexes were prepared indirectly. Ligand dpm gives complexes of the formula [Pd(dpm)X]2. With dam, the nature of the product depends upon the identity of the halogen; with X = Cl, Br the products are [Pd(dam)X]2CO, but the iodo derivative is [Pd(dam)I]2. N.m.r. spectroscopy suggests that [Pd(dam)I]2 has a structure different to the dpm complexes. �� [Pd(dam)Cl]2CO,3C6H14 is tetragonal, space group P4I, a 22.0458(1), c 14.4345(1) Ǻ containing four dimer units per unit cell. The structure was refined to R 0.096 and Rw 0.097 for 1698 independent reflections. The crystals are molecular being composed of discrete dimeric molecules of the complex and solvent. The palladium coordination is approximately square planar with two trans arsenic atoms, terminal halogen and the bridging carbonyl group which is common to both metal environments. There is no twist about the Pd-Pd axis so the Pd,As, unit is planar. The Pd-Pd distance of 3.274(8) Ǻ is too long for a direct metal-metal bond. However, the compound is diamagnetic so spin pairing must occur through the unusual carbonyl bridge.
