The crystal and molecular structures of (C12H8N2)Mo(CO)4 and (C12H8N2)Cr(CO)4 are reported. They crystallize in the space group C2/m and are isomorphous with each other. The unit cell dimensions for (C12H8N2 Cr(CO)4 are a=15.404(2), b=12.091(2), c=8.223(2) A, 3=108.70(2)0, and V=1450.6(9) A3, while for (C12H8N2)Mo(CO)4 are a=15.546(6), b=12.086(4), c=8.269(1.) A, β= 107.37(2)0 and V=1482.9(l.5) A3, and both Z=4. Final R=0.040 Rw=0.050 for (C12H8N2)Cr(CO)4 and R=0.034 Rw=0.053 for (C12H8N2)Mo(CO)4.
