Self-Assembly of a Series of Novel Metal−Organic Compounds Containing Ferrocenecarboxylate Components

Abstract

Using FcCOONa (Fc = (eta(5)-C(5)H(5))Fe(eta(5)-C(5)H(4))) as starting material, we obtained an unprecedented metal-organic coordination polymer containing ferrocenecarboxylate components [[Pb(2)(FcCOO)(eta(2)-FcCOO)(mu(2)-eta(2)-FcCOO)(mu(3)-eta(2)-FcCOO)(CH(3)OH)].1.5CH(3)OH.H(2)O](n) (1), tetramer [Zn(4)(mu(2)-FcCOO)(6)(mu(4)-O)] (2), and coordination polymers [Pb(FcCOO)(mu(2)-FcCOO)(bpe)](n) (3) (bpe = 1,2-bis(4-pyridyl)ethene), [[Zn(FcCOO)(2)(bpt)].2.5H(2)O](n) (4) (bpt = N,N'-bis(3-pyridylmethyl)thiourea), and [Zn(FcCOO)(eta(2)-FcCOO)(bbp)](n) (5) (bbp = 4,4'-trimethylene-dipyridine). Compounds 1 and 2 are formed by ferrocenecarboxylate units coordinating with Pb(II) or Zn(II). In polymer 1, ferrocenecarboxylate units have four kinds of coordinate modes; just these novel coordinate modes lead to the unprecedented one-dimensional polymer where two kinds of rhomboids are arranged alternatively along the chain. Compound 2 is a tetramer, in which a distinct connectivity of the six ferrocene units is established through the four Zn atoms. Compounds 3-5 are obtained by organic ligands bridging Pb(II) or Zn(II), leading to a new type of metal-organic coordination polymer.

The syntheses, crystal structures and optical limiting effects of transition metal adducts bridged by bipyridyl-based ligands

“…The asymmetric unit consists of a HgI 2 molecule and a bpt ligand binding to Hg with pyridyl group. The Hg-I1, Hg-I2, and Hg-N bond lengths are 2.6838(9), 2.7125 (8), and 2.591(7) Å , respectively, which are similar to those of the related polymers [HgI 2 (L)] n (Hg-I ranging from 2.6430(5) to 2.6683(8) Å , and Hg-N from 2.3626(6) to 2.457(6) Å [16][17][18][19][20][21]); The Hg-S bond lengths of 2.548(2) Å are all within normal values (2.129-3.261 Å [22][23][24][25]). The formation of Hg-S bond may be a consequence that Hg(II) (soft acid) is com- 3 The X-ray single-crystal data for the title compounds were collected using Mo Ka radiation (k = 0.71073 Å ) on a Rigaku RAXIS-IV image plate area detector.…”

“…The hydrogen atoms were located theoretically and not refined. paratively easier to coordinate with bpt through S atom (soft base) than Co(II), Mn(II) [17], or Zn(II) [18]; The angles around Hg center range from 91.15(18)°to 130.88(3)°. Two bpt ligands and two Hg atoms consist of an interesting, ring-like structure unit with dimensions of 8.680 · 7.471 Å (Hg1-Hg1A · C6-C6A).…”

“…As a versatile functionalized ligand, ferrocenecarboxylate is widely used for the construction of heterometallic complexes with other metals. Among them, most of heterodimetallic complexes, such as mononuclear complexes [14][15][16], polymers [17], clusters [18], and MOFs [19] are reported in the last few years.…”

Substitution, Addition, and Recombination Reactions of Precursor Complexes with Ferrocenyl Carboxylate Units
