          percent chloride, based on silver, and having greater than 50               
          percent of their surface area provided by {100} crystal faces,              
          wherein                                                                     
               (i) a first fraction which comprises from 10-90 wt% of the             
          silver halide grains, based on total radiation-sensitive silver             
          halide in the layer, consists of grains which have a central                
          portion accounting for up to 99 percent of total silver which               
          contains at least 10-7 mole of a hexacoordination metal complex             
          which satisfies formula (I) per mole of silver and less than 10-10          
          mole of a hexacoordination metal complex which satisfies formula

          silver halide grains, based on total radiation-sensitive silver             
          halide in the layer, consists of grains which have a central                
          portion accounting for up to 99 percent of total silver which

          independently selected, provided that at least four of the                  
          ligands are anionic ligands, and at least one of the ligands is a           
          cyano ligand or a ligand more electronegative than a cyano                  
          ligand;
