Bridging halide ligands

A potential solution to this problem is evident in the recent synthesis of some dinuclear Cu(II)2L complexes with bridging halide ligands (16). These complexes are based on the ligand... 

X, is a terminal halide ligand and Xb is a bridging halide ligand d is the displacement (A) of the metal atom from the plane through the three ligand atoms. 

Preparation of the complexes CdX2L2 (X = C1, Br, I or SCN L = acetamide) has been reported. IR evidence indicates bridging halide ligands, with L coordination via O and N.353 The crystal structure of dichlorobis(N,N-dimethyIacetamide)zinc shows zinc tetrahedrally... 

Simple neutral Au halides, AuX (X = Cl, Br, I), are all polymers with bridging halide ligands. The complex ions [AuX2] , disproportionate in aqueous solution according to equation (1), where X = Cl, Br, or SCN, are stable when X = CN. The ions [AuX2] can be stabilized in the presence of excess of halide or pseudohalide ions. 

In the case of the platinum complexes with bridging halide ligands, the coordination to the silver center results in the loss of the planarity of the platinum skeleton while in the derivative with bridging pentafluorophenyl ligands which is not planar, a decrease in the dihedral angle between the coordination planes of both platinum centers occurs in order to facilitate the coordination of both platinum atoms to the silver center (Fig. 8). The Pt-Ag bonds in these trinuclear complexes form an angle with the perpendicular to the platinum coordination plane in the range of 10-...
