MeCN from [W(CH3CN)3(CO)2(NO)][BF4] led to the following cationic compounds incorporating mono- and bidentate coordinated phosphane ligands: cis,cis-[W(CO)2(NO)(Ph2PR)(η2-Ph2PR)][BF4], [R = 2-pyridyl (9a), 2-picolyl (11)], cis,cis-[W(CO)(NO)(η2-Ph2Ppy)2][BF4] (20), trans,trans-[W(CO)(NO)(η2-Ph2Ppy)2][BPh4] (21), fac-[W(CO)2(NO)(Me2Ppy)3][BF4] (16), fac-[W(CO)2(NO)(Me2P-tert-Bupy)3][BF4] (18), cis,c
吡啶基膦的配位化学,例如 2-(6-tert-butylpyridyl)diphenylphosphane (Ph2P-tert-Bupy) (6) 和 2-(6-tert-butylpyridyl)二甲基膦 (Me2P-tert-Bupy) (7) 对报道了许多亚硝基钨配合物。[W(CH3CN)3(CO)2(NO)][BF4] 中松散配位的 MeCN 的置换导致以下阳离子化合物结合了单齿和双齿配位磷烷配体:顺式,顺式-[W(CO)2( NO)(Ph2PR)(η2-Ph2PR)][BF4],[R = 2-吡啶基 (9a),2-吡啶甲基(11)],顺,顺-[W(CO)(NO)(η2-Ph2Ppy) 2][BF4] (20), trans,trans-[W(CO)(NO)(η2-Ph2Ppy)2][BPh4] (21), fac-[W(CO)2(NO)(Me2Ppy)3 ][BF4] (16)
