found for the nitrogen bound NCS − ligand. Mer,trans -[ReCl 2 (NCS) (Me 2 PhP) 3 ] isomerizes to mer,cis -[ReCl 2 (NCS) (Me 2 PhP) 3 ] at longer reaction periods. The cis complex crystallizes in the monoclinic space group P 2 1 / n , Z = 4. A unit cell of dimensions a=14.824(7), b = 13.158(2), c = 16.212(7) A , β = 112.92(2)° was determined for this compound. The rhenium atom is six-coordinate with
摘要[ReCl 3(Me 2 PhP)3]与过量的KSCN或三甲基甲硅烷基异硫氰酸酯的反应导致仅取代一个氯配体。最初,形成mer,trans- [ReCl 2(NCS)(Me 2 PhP)3]。该化合物在单斜空间群P 2 1 / n中结晶,其晶胞尺寸为a = 14.992(2),b = 10.846(1),c = 19.117(6)A,β= 112.89(2)°,Z = 4。氯配体彼此以反位配位。对于氮结合的NCS-配体,发现ReN键长为2.071(4)A。Mer,trans-[ReCl 2(NCS)(Me 2 PhP)3]在更长的反应时间下异构化为mer,cis-[ReCl 2(NCS)(Me 2 PhP)3]。顺式复合物在单斜空间群P 2 1 / n中结晶,Z =4。尺寸为a = 14.824(7),b = 13.158(2),c = 16.212(7)A,β= 112.92(测定该
