Reaction of AgAc with bzdmpymtH in MeOH resulted in the title compound [Ag(bzdmpymt)]6·2MeOH(1·2MeOH),which was structurally characterized by elemental analysis,IR,and single-crystal X-ray diffraction analysis.1·2MeOH belongs to the triclinic system,space group Pī,with a = 10.930(2),b = 11.646(2),c = 16.794(3) ,α = 103.97(3),β = 97.07(3),γ = 97.94(3)°,V = 2027.2(7) 3,Z = 1,μ = 1.629 mm-1,Dc = 1.710 mg/m3,T = 193(2) K,C80H86Ag6N12O2S6,Mr = 2087.25,F(000) = 1044,S = 1.034,R = 0.0355 and wR = 0.0709.In 1·2MeOH,six silver(I) atoms are held together by six bzdmpymt ligands through N and S atoms to form a water-wheel-shaped structure.Each Ag atom is coordinated by two S atoms from two bzdmpymt ligands and one N atom from the third bzdmpymt ligand,giving a trigonal planar coordination geometry.Interactions between the CH3 group of bzdmpymt ligand and one pyrimidyl nitrogen atom in an adjacent molecule afford a one-dimensional hydrogen-bonding chain running along the b axis.The luminescent property of 1·2MeOH was also investigated.
The reaction of [Et4N]2WOS3 with three equiv.of CuI and dmpzm in MeCN afforded [WOS3Cu3I(dmpzm)2]·2(MeCN)0.5(1·2(MeCN)0.5) while that of [PPh4]2WS4 with four equiv.of CuI in DMF/MeCN followed by the addition of two equiv.of dmpzm in MeOH gave rise to [WS4Cu4I2(dmpzm)2]·DMF(2·DMF).Both compounds were characterized by elemental analysis,IR,and single-crystal X-ray diffraction analysis.1·2(MeCN)0.5 crystallizes in triclinic,space group P1-with a = 11.4552(5),b = 11.6735(3),c = 16.2278(9) ,α = 99.537(9),β = 101.986(2),γ = 118.464(13)o,V = 1775.5(3)3,Z = 2,μ = 6.080 mm-1,Dc = 1.983 Mg/m3,T = 193(2) K,C24H35Cu3IN9OS3W,Mr = 1063.22,F(000) = 1018,S = 1.060,R = 0.0376 and wR = 0.0870.2·DMF belongs to the orthorhombic system,space group Pmn21 with a = 22.145(4),b = 11.464(2),c = 7.7370(15) ,V = 1964.2(6)3,Z = 2,μ = 6.865 mm-1,Dc = 2.189 Mg/m3,T = 193(2) K,C25H39Cu4I2N9OS4W,Mr = 1301.72,F(000) = 1226,R = 0.0632,wR = 0.1706 and S = 1.130.1·2(MeCN)0.5 consists of one CuI and two [Cu(dmpzm)]+ fragments that are linked by [WOS3]2-species via six Cu-S bonds,forming a nido-like [WS3Cu3] core.2·DMF contains a saddle-shaped [WS4Cu4] core with two iodides coordinated at two Cu centers in a cis position and two dmpzm ligands being chelated at another two Cu centers in a cis position.
