In the title compound, {[Cu(C5H6O4)(ClO4)(C16H22N4)]ClO4·2H2O}n, square-pyramidally coordinated Cu atoms with perchlorate and dimethylmalonate ligands are connected into cationic sinusoidal coordination polymer chains by doubly protonated bis(3-pyridylmethyl)piperazine (3-bpmp) ligands. The chains aggregate into pseudo-layers parallel to the (101) crystal planes by N-H
O hydrogen bonding. Unligated perchlorate anions and water molecules of crystallization provide additional hydrogen bonding between pseudo-layers.
All chemicals were obtained commercially, except for 3-bpmp which was
synthesized by a literature method (Pocic et al., 2005). Copper
perchlorate hexahydrate (19 mg, 0.051 mmol) and dimethylmalonic acid (7 mg,
0.05 mmol) were dissolved in 3 ml water in a glass vial. A 1 ml aliquot of a
1:1 water:ethanol solution was carefully layered onto the aqueous solution,
followed by
3 ml of an ethanolic solution of 3-bpmp (27 mg, 0.10 mmol). Blue blocks of the
title compound formed after 1 week.
All H atoms bound to C atoms were placed in calculated positions, with C—H =
0.95 - 0.99 Å and refined in riding mode with Uiso =
1.2Ueq(C) or 1.5Ueq(C) for methyl C atoms.
All H atoms bound to O atoms were found via Fourier difference map,
restrained with O—H = 0.89 Å, and refined with
Uiso=1.2Ueq(O). All H atoms bound to N atoms were found
via Fourier difference map, restrained with N—H = 0.89 Å, and
refined with Uiso=1.2Ueq(N).

Special details top
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell e.s.d.'s are taken
into account individually in the estimation of e.s.d.'s in distances, angles
and torsion angles; correlations between e.s.d.'s in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s.
planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor
wR and goodness of fit S are based on F2, conventional
R-factors R are based on F, with F set to zero for
negative F2. The threshold expression of F2 >
σ(F2) is used only for calculating R-factors(gt) etc.
and is not relevant to the choice of reflections for refinement.
R-factors based on F2 are statistically about twice as large
as those based on F, and R- factors based on ALL data will be
even larger. |

In comparison to coordination polymers based on the rigid rod tether 4,4'- bipyridine, extended phases based on the flexible and hydrogen-bonding capable bis(3-pyridylmethyl)piperazine (3-bpmp) ligand are much less common (Johnston et al., 2008).
The asymmetric unit of the title compound contains a divalent copper atom, two halves of two 3-bpmp molecules protonated at their piperazinyl nitrogen atoms, one dimethylmalonate dianion, one bound and one unbound perchlorate ion and two water molecules of crystallization (Figure 1). The Cu atoms are square pyramidally coordinated in a {CuN2O3} arrangement, with the basal plane occupied by two cis N atom donors from two crystallographically distinct 3-bpmp ligands and two cis O atom donors from a dimethylmalonate ligand in a 1,3-chelating binding mode. The apical position is filled by a ligated perchlorate anion.
The 3-bpmp ligands link the Cu atoms into sinusoidal cationic coordination polymer chains with formulation [Cu(3-bpmpH2)(dimethylmalonate)(ClO4)]nn+ (Figure 2), in which the through ligand Cu···Cu contact distance is 15.441 Å. The "wavelength" of this chain, defined by unbridged Cu···Cu contacts, is 15.991 Å. The chains are aligned parallel to the [1 0 1] crystal direction.
Neighboring chains interdigitate and aggregate into a pseudolayer (Figure 3) parallel to the (1 0 1) crystal plane by N—H···O hydrogen bonding between protonated piperazinyl N atoms and unligated dimethylmalonate O atoms. These stack into three dimensions (Figure 4) through additional hydrogen bonding patterns involving unligated perchlorate anions and water molecule dimers, and dimethylmalonate O atoms within the coordination polymer chains.
