طراحی و سنتز پلیمر های کئوردینانسیونی متخلخل یا چارچوب های فلز- آلی به علت ساختارهای جالب این ترکیبات و قابلیت های کاربردی آنها برای ذخیره و جداسازی گاز، کاتالیز، تشخیص و جداسازی انانتیومرها، خواص مغناطیسی، تنظیم لومینسانس و غیره توجه زیادی را به خود جلب کرده است. اخیرا مشخص شده است که برخی لیگاندهای آلی مسطح صلب مثل ایمیدازول-5،4-دی کربوکسیلیک اسید (h3idc) برای تشکیل چارچوب های فلز- آلی مناسب ...

The study aims at providing a strategy to synthesize self assembled structures where a coordination complex has been touted as the building block and to accomplish such a strategy, several coordination complexes of pyridineamide based bidenate and tridentate ligands have been used as the building blocks. Further, such building blocks either offer H-bond donor/acceptors groups (phenol, catechol ...

A binucleating ligand has been prepared that contains an SCS pincer and three oxygen donor atoms in a partial crown ether loop. To enable metalation with Ni(0), a bromoarene precursor was used and resulted in the formation of a nickel-bromide complex in the SCS pincer portion of the ligand. Reaction of the nickel complex with a lithium salt yielded a heterobimetallic complex with bromide bridgi...

Four heterobimetallic U(vi)/M(ii) (M = Mn, Co, Cd) carboxyphosphonates have been synthesized. M(2)[(UO(2))(6)(PO(3)CH(2)CO(2))(3)O(3)(OH)(H(2)O)(2)]·16H(2)O (M = Mn(ii), Co(ii), and Cd(ii)) adopt cubic three-dimensional network structures with large cavities approximately 16 Å in diameter that are filled with co-crystallized water molecules. [Cd(3)(UO(2))(6)(PO(3)CH(2)CO(2))(6)(H(2)O)(13)]·6H(2...

Similar reactions of 2,6-dipicolinoylbis(N,N-diethylthiourea) (H2L(a)) with: (i) Ni(NO3)2·6H2O, (ii) a mixture of Ni(NO3)2·6H2O and AgNO3, (iii) a mixture of Ni(OAc)2·4H2O and PrCl3·7H2O and (iv) a mixture of Ni(OAc)2·4H2O and BaCl2·2H2O give the binuclear complex [Ni2(L(a))2(MeOH)(H2O)], the polymeric compound [NiAg2(L(a))2]∞, and the heterobimetallic complexes [Ni2Pr(L(a))2(OAc)3] and [Ni2Ba(...

The title compound, [FePt(C(9)H(9)NO(2)S)(C(18)H(15)P)(C(25)H(22)P(2))(CO)(3)], represents a rare example of an isonitrile-bridged heterobimetallic complex (here Pt and Fe) and is an inter-esting precursor for the preparation of heterodinuclear μ-amino-carbyne complexes, since the basic imine-type N atom of the μ(2)-C=N-R ligand readily undergoes addition with various electrophiles to afford im...
