  Water is the most important liquid in the Universe. At the same time it is
the most anomalous liquid. It demonstrates several dozens of anomalies, among
which are density anomaly, diffusion anomaly etc. Anomalous behavior of water
is a topic numerous publications. However, most of the publications investigate
the anomalous behavior of water in the vicinity of critical points: the
liquid-gas critical point and the second hypothetical critical point in
supercooled region. Here we analyze experimental data on such properties of
water as heat capacity, speed of sound, dynamic viscosity and thermal
conductivity. We show that these properties demonstrate anomalous maxima and
minima in a region which is far from both critical points. Therefore, we find a
novel region of anomalous properties of water (anomalous triangle) which cannot
be related to critical fluctuations. We also perform a molecular dynamics
simulations of this region with two common water models - SPC/E and TIP4P - and
show that these models fail to describe the novel anomalous region.
