Spin canting in the 3D anionic dicyanamide structure (SPh3)Mn(dca)3 (Ph=phenyl, dca=dicyanamide)

Through use of the SPh3+ (Ph = phenyl, C6H5) cation as a molecular template, a new three-dimensional Mn(dca)(3)(-) [dca = dicyanamide, N(CN)(2)(-)] anionic structure has been crystallized. At room temperature, (SPh3)Mn(dca)(3) (1) crystallizes in the monoclinic space group P2(1)/c, with a = 11.7079(5) Angstrom, b = 12.8554(5) Angstrom, c = 16.8605(6) Angstrom, beta = 100.666(2)degrees, and V= 2493.8(3) Angstrom(3). Magnetic susceptibility measurements indicate that this salt exhibits a spin canted long range antiferromagnetically ordered ground state below 2.5 K.
