9-Benzyl-6-benzyl­sulfanyl-9H-purin-2-amine

In the title compound, C₁₉H₁₇N₅S, the dihedral angles between the purine ring system (r.m.s. deviation = 0.009 Å) and the S-bound and methyl­ene-bound phenyl rings are 74.67 (8) and 71.28 (7)°, respectively. In the crystal, inversion dimers linked by pairs of N—H...N hydrogen bonds generate R₂²(8) loops. C—H...N inter­actions link the dimers into (100) sheets.

(Benzyl­diphenyl­phosphane-1κP)[μ-bis(diphenylphosphan­yl)methane-2:3κ²P:P′]nona­carbonyl-1κ³C,2κ³C,3κ³C-triangulo-triruthenium(0)

The asymmetric unit of the title compound, [Ru₃(C₁₉H₁₇P)(C₂₅H₂₂P₂)(CO)₉], consists of two independent mol­ecules. The bis­(di­phenyl­phosphan­yl)methane ligand bridges an Ru—Ru bond and the benzyl­diphenyl­phosphane ligand binds to the third Ru atom. The Ru—Ru bond cis to the benzyl­diphenyl­phosphane ligand is the longest of the three Ru—Ru bonds in both mol­ecules. In the crystal, mol­ecules are linked by C—H...O hydrogen bonds, forming layers parallel to the ac plane. C—H...π contacts further stabilize the crystal packing.

Crystal structure of bromido­bis­(naph­thal­en-1-yl)anti­mony(III)

In the title compound, [SbBr(C₁₀H₇)₂], the Sb^III atom has a distorted trigonal–pyramidal coordination geometry and the planes of the two naphthalene ring systems make a dihedral angle of 80.26 (18)°. An intra­molecular C—H...Br hydrogen bond forms an S(5) ring motif. In the crystal, weak C—H...Br inter­actions link the mol­ecules into helical chains along the b-axis direction.
