 Title    Darstellung und Kristallstruktur von Rb6Sn2S7 New Chalcogenometallates with Binuclear Anions, I: Preparation and Crystal Structure of Rb6Sn2S7  
 Abstract    Colorless crystals of the new thiostannate Rb6Sn2S7 were obtained by reacting a stoichio­ metric melt of Rb2S, Sn and S at 700°C. The compound is orthorhombic, oP60, s.g. f '2,2,2, (No. 19) with a = 9.982(4), b = 13.45(1), c = 15.20(1) A; Z = 4. The crystal structure was determined from diffractometer data and refined to a conventional R of 0.043 (1380 Fo's, 137 variables). The crystal structure contains dimeric anions, [Sn2S7]2 -, which are built up by slightly distorted SnS4 tetrahedra sharing a common sulfur atom. The mean Sn-S bond length calculates as 2.384 Ä, the bond angle on the bridging S is 110.4°. The structure contains six independent Rb-cations which are coordinated to 5-6 sulfur atoms in irregular configurations. Neue Chalkogenometallate mit binuklearen Anionen, I:

 Title    Synthesis, Structural and EPR Investigations on Bis(tetraphenylphosphonium)- bis(l,2-dithiosquarato)oxovanadate(IV), (Ph4P)2[VO(dtsq)2]  
 Abstract    The molecular structure and EPR studies of bis(tetraphenylphosphonium)bis(1,2-dithiosquarato)oxovanadate(IV) are reported. (Ph4P)2[VO(dtsq)2] crystallizes in the mono­ clinic spaceogroup P2,/n with the unit cell parameters a = 10,9820(2), b = 15,4620(3), c = 14,5050(3) Ä, ß = 95,700(8)°, Z = 2. The g and hyperfine coupling tensors Av obtained from the EPR spectra in liquid and frozen solution are used to characterize the properties of the molecular orbital containing the unpaired electron and are compared to those obtained from EHT-MO calculations.
