(PhAsNSN)2 (1) reacts with M(CO)4(C7H8) (M = a Cr, b Mo) to yield (PhAsNSN)2M(CO)4 (2). 2a and 2b are dark red air stable complexes. 2b was characterized by X-ray diffraction.Crystals of 2b are monoclinic, space group C2/c, with a = 2884.7(4), b = 1166.2(2), c = 1344.1(2) pm, β = 104.81(2) deg and Z = 8.The molecule exhibits approximate mm (C2v) symmetry with mean bond lengths: Mo-As 255.1, Mo-C 201.8, As-N 186.2 and S-N 152.8 pm. - Key words: X-Ray, Chromium, Molybdenum, Heterocycles
