14871-92-2, Name is (2,2′-Bipyridine)dichloropalladium(II), belongs to catalyst-palladium compound, is a common compound. Recommanded Product: (2,2′-Bipyridine)dichloropalladium(II)In an article, once mentioned the new application about 14871-92-2.

Syntheses and crystal structure determinations of [Pd(bpy)([9]aneS3)][PF6]2 (bpy = 2,2′-bipyridine; [9]aneS3 = 1,4,7-trithiacyclononane) and [Pt(phen)([9]aneS3)][PF6]2 (phen = 1,10-phenanthroline) are reported. The Pd compound (C16H20N2S3PdP2F12) crystallizes in triclinic space group P1- (No. 2), with a = 10.376(3) A, b = 10.810(2) A, c = 10.907(2) A, alpha = 84.25(1)°, beta = 87.25(2)°, gamma = 84.89(2)°, Dc = 2.009 g cm**-3, and Z = 2; the Pt compound (C18H20N2S3PtP2F12) crystallizes in orthorhombic space group Pbca (No. 61), with a = 15.422(3) A, b = 10.618(2) A, c = 31.335(6) A, Dc = 2.189 g cm**-3, and Z = 8. Each structure features a five-coordinate metal center in a distorted square-pyramidal geometry. Two diimine nitrogensand two of the S-donors of [9]aneS3 are bound in the square plane, (M-N2.06-2.07 A; M-S 2.27-2.29 A), whereas the third sulfur of the thia crown ether occupies the apical position (Pd-S 2.81 A; Pt-S 2.82 A). The room-temperature (1)H NMR solution spectrum of each complex shows an AA’BB’ pattern in the methylene region. The NMR spectral properties of [Pt(phen)([9]aneS3)][PF6]2 between room temperature and -91°C in acetone-d6 solution are interpreted in terms of relatively rapid intracomplex rearrangements (DeltaG(.++.) .apprx. 38 kJ mol**-1; Tc= -80°C) similar to the nuclear motions associated with the formation and decay of the transition state in a Pt(II) associative substitution reaction.
