New complexes of general formula Pd(L-L)(CO2CH3)2 (L-L=1,10-phenanthroline 1; 2,9-dimethyl-1,10-phenanthroline 2; 4,7-dimethyl-1,10-phenanthroline 3; 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline 4, 3,4,7,8-tetramethyl-1,10-phenanthroline 5; and 4,7-diphenyl-1,10-phenanthroline 6) were prepared either by exchange reaction between Pd(bipyridine)(CO2CH3)2 7 and the appropriate free ligand or by reacting Pd(L-L)Cl2 suspended in MeOH under carbon monoxide, at room temperature, in the presence of a base. The structure of 1 was determined ab initio from X-ray powder diffraction data by using a simulated annealing technique and refined by the Rietveld method. 1 crystallizes in the orthorhombic Pbca space group with cell parameters a=8.0787(4), b=16.2797(8), c=22.843(1) A and Z=8.
