Abstract

monoclinic, space group P21, Z = 2), (IX) (orthorhombic, Pna21, Z = 4), and the Sb V compound (V) (P1, Z = 1) are determined by single crystal XRD. The compounds contain discrete cationic [Zn(NH3)4] 2+ , [Zn(NH3)6] 2+ , and [Mn(NH3)6] 2+ ammonia complexes. In the anionic structure corner-connected trigonal-pyramidal SbS 3 and SbSe 3 are the characteristic building units. (I) and (VII) contain two-dimensional polymeric anions, in the latter with Zn 2+ cations incorporated in a selenidoantimonate(III) network. The polymeric anion in (IX) is a helical chain while (V) is a molecular compound and contains dinuclear anions [S3Sb-S-Zn(NH3)3] 2-. (VII) is a semiconductor with an optical band gap of 2.05 eV. -(KYSLIAK, O.; BECK*, J.; Z. Anorg. Allg. Chem. 639 (2013) 15, 2860-2867, http://dx.
