Over the past decades, considerable attentions have been paid
to rational design and synthesis of novel coordination polymers
with intriguing structure and diverse functions [1,2], owing to its
promising application as functional materials in many fields [3,4].
As two typical bridging groups affording magnetic clusters and
polymers, carboxylate and azido anions have been widely used due
to their rich coordination modes as well as diverse magnetic
coupling patterns [5–7], and therefore many unique carboxylate-
containing ligands have been developed to construct magnetic
coordination compounds.
Recently, some coordination compounds derived from azide
and zwitterionic dicarboxylate ligands were reported [7], which
demonstrates that using zwitterionic carboxylates as ligands is an
efficient synthetic strategy toward mixed azide- and carboxylate-
bridging systems [7,8]. Normally when zwitterionic carboxylates
are used as neutral organic ligands to construct metal–organic
compounds, additional anions are necessary for charge balance [9].
Compared with rigid ligands, flexible ligands can form some
unique and interesting frameworks because it can freely bend and
rotate in the assembly process [8a,10].

2. Experimental
36
Materials and physical measurements: 1,4-Bis(pyridinil-3- 37
carboxylato)-l,4-dimethylbenzene (L) was prepared according to 38
the literature [11]. Other chemicals are commercially available 39
and were used as received. Elemental analysis was carried on a 40
Perkin-Elmer 240C analyzer. IR spectrum was measured on a 41
Tensor 27 (Bruker) FT-IR spectrometer with KBr pellets. The X-ray 42
powder diffraction (XRPD) experiments were carried out on a 43
Rigaku D/Max-2500 diffractometer, operated at 40 kV and 100 mA, 44
using a Cu-target tube and a graphite monochromator. Simulation 45
of the PXRD spectra were conducted based on the single-crystal 46
data and diffraction-crystal module of the Mercury (Hg) 47
program available free of charge in Internet (http://www.iucr.org). 48
Magnetic data were collected using crushed crystals of the sample 49
on a Quantum Design MPMS-XL SQUID magnetometer.

Synthesis of L:L was prepared in a way similar to that reported 51
in literature [11]. 1,4-Bis-bromomethylbenzene (1.75 g, 10 mmol) 52
was dissolved in the acetone solution of ethyl nicotinate (2.83 mL, 53

Single-crystal X-ray diffraction analysis reveals that 1 crystal-
lized in triclinic P-1 space group. The asymmetric unit comprises of
one crystallographically independent Mn(II) ion (Mn1), two
independent halves of Mn(II) ions (Mn2 and Mn3), four azido
anions, one L ligand and two uncoordinated water molecules, as
displayed in Fig. 1a. Mn1 locates in a disordered coordination
environment defined by four azido nitrogen atoms (N1, N4, N7 and
N10) and two cis carboxylate oxygen atoms (O2 and O3). Mn2 and
Mn3 both assume the trans-octahedral [N4O2] coordination
environment defined by four equatorial azido nitrogen atoms
(N7, N7B, N10 and N10B for Mn2, N1, N1A, N4 and N4A for Mn3)
and two axial carboxylate oxygen atoms (O4 and O4B for Mn2, O1
and O1A for Mn3) (Fig. 1b). The Mn-N distances for Mn2 and Mn3

Cystallographic Studies: X-ray diffraction data were collected
on a SCX-mini diffractometer at 293 K with graphite monochro-
˚
mated Mo-Ka radiation (l = 0.71073 A) by an v scan mode. The
program SAINT [12] was used for the integration of the diffraction
profiles. Absorption corrections were carried out by using multi-
scan program SADABS [13]. The structures were solved by direct
method and refined by full-matrix least-squares technique using
SHELXTL [14]. The positions of metal atoms were located from E-
maps by direct-method and other non-hydrogen atoms were
refined with anisotropic displacement parameters. The hydrogen
atoms of the ligands were generated theoretically onto specific
atoms and refined isotropically with fixed thermal factors.

conformation with respect to the 1,4-dimenthylbenzene, leading
to a zigzag shape for the ligand. Each chain is linked with adjacent
four identical chains through L ligands to give a complicated 3D
network (Fig. 2a). Large ‘‘empty’’ space related to the L linkers is
observed for the single network, but is filled by the 2-fold
interpenetration occurred between two equivalent 3D networks

The global AF behavior of 1 can be interpreted by magneto- 151
structural relationship. The Mn(II) ions in 1 are bridged by EO azido 152
and syn,syn carboxylate of L ligand. It is well known that syn,syn 153
carboxylate mediates AF interaction, while the nature of the 154
coupling transmitted by EO mode depends on the M–Nazido–M 155
angle [5c]. For Mn(II) ions, the ferromagnetic coupling appears over 156
the crossover angle of 988 and reaches its top at 1068 [5c]. In 157
polymer 1, the bridging angle of EO azido is 94.698 for Mn(1)–N(4)– 158
Mn(3) and 95.088 for Mn(1)–N(1)–Mn(3); while the bridging angle 159
of EO azido is 94.278 for Mn(1)–N(7)–Mn(2) and 93.128 for Mn(1)– 160
N(10)–Mn(2). All of these angles are smaller than 988 and therefore 161
conduct AF coupling. The AF exchange interaction mediated by EO 162
azido and syn,syn carboxylate of L ligand should account for the 163

pattern and the simulated pattern as displayed in Fig. 3 indicates
that bulk-synthesized materials and the as-grown crystals are
homogeneous.
